When adding a Job to scheduler: Value cannot be null, Job class cannot be null?

My question is very similar to:
Quartz.net - "Job's key cannot be null"
However its different setup as I am using Rest API.
I am able to run a job when adding through Startup.cs however when I call API to add job using javascript it fails with below error:
ERROR:
System.ArgumentNullException: Value cannot be null. (Parameter 'typeName')

SETUP:
In VS, I created Quartz REST API and front end in a single project. Running the project loads webpage with Jobs and API running in the background.
All controller endpoints work except AddJob. (i.e. get jobs, view job details, pause, resume, trigger, delete)
Dependency:
Quartz.Extensions.Hosting 3.3.3
JobsController.cs
quartznet/JobsController.cs at main · quartznet/quartznet · GitHub
[HttpPut]
[Route("{jobGroup}/{jobName}")]
public async Task AddJob(string schedulerName, string jobGroup, string jobName, string jobType, bool durable, bool requestsRecovery, bool replace = false)
{
var scheduler = await GetScheduler(schedulerName).ConfigureAwait(false);
var jobDetail = new JobDetailImpl(jobName, jobGroup, Type.GetType(jobType), durable, requestsRecovery);
await scheduler.AddJob(jobDetail, replace).ConfigureAwait(false);
}
HelloWorldJob.cs:
https://andrewlock.net/using-quartz-net-with-asp-net-core-and-worker-services/
Startup.cs: (Adds a job without API and runs it using trigger at start)
void ConfigureHostQuartz(IServiceCollection services)
{
services.AddQuartz(q =>
{
q.UseMicrosoftDependencyInjectionScopedJobFactory();
var jobKey = new JobKey("HelloWorldJob");
q.AddJob<HelloWorldJob>(opts => opts.WithIdentity(jobKey));
q.AddTrigger(opts => opts
.ForJob(jobKey)
.WithIdentity("HelloWorldJob-trigger")
.WithCronSchedule("0/5 * * * * ?"));
});
services.AddQuartzHostedService(
q => q.WaitForJobsToComplete = true);
}
Html/Javascript front end:
Following this example:
Tutorial: Call an ASP.NET Core web API with JavaScript | Microsoft Docs
<form action="javascript:void(0);" method="POST" onsubmit="addJob()">
<input type="text" id="add-name" placeholder="New job">
<input type="submit" value="Add">
</form>
<script>
function addJob() {
const addNameTextbox = document.getElementById('add-name').value.trim();
const item = {
jobType: "HelloWorldJob",
durable: true,
requestsRecovery: false,
replace: false
};
fetch(`${uri}/DEFAULT/${addNameTextbox}`, {
method: 'PUT',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(item)
})
.then(response => console.log(response))
.then(() => {
getJobs();
addNameTextbox.value = '';
})
.catch(error => console.error('Unable to add job.', error));
}
</script>
I have tried updating the API to include jobType in url, then it gives different error:
Job class cannot be null
at Qurtz.Impl.JobDetilImpl.set_JobType(Type value)

You need to supply assembly qualified name as job type. Problems is here:
jobType: "HelloWorldJob",
jobType should be something like "MyNameSpace.JobType, MyAssembly" - you can probably get this written to console with Console.WriteLine(typeof(HelloWorldJob).AssemblyQualifiedName) - you can ignore the version etc, only type name with namespace and assembly name are needed.
Please also note that your setup has security implications as you allow CLR types to be passed from the UI.

API controller changes:
As mentioned by Marko above, jobType needs fully qualified name, assembly reference is not however necessary in my case as I have jobs in same assembly.
[HttpPut]
[Route("{jobGroup}/{jobName}/{jobType}/{replace}/new")]
public async Task NewJob(string schedulerName, string jobGroup,
string jobName, string jobType, bool replace = false)
{
//Note: Job added without a trigger must be durable.
var scheduler = await GetScheduler(schedulerName).ConfigureAwait(false);
var jobDetail = new JobDetailImpl(jobName, jobGroup,
Type.GetType("QuartzApi.Jobs." + jobType), true, false);
await scheduler.AddJob(jobDetail, replace).ConfigureAwait(false);
}
JavaScript fetch query changes:
Removed JSON body tag and added extra parameters to url. Note its a job without trigger. At a later stage jobType can be a variable, for now its included in fetch string.
function addJob() {
const addNameTextbox = document.getElementById('add-name').value.trim();
fetch(`${uri}/DEFAULT/${addNameTextbox}/HelloWorldJob/false/new`, {
method: 'PUT',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
})
.then(response => console.log(response))
.then(() => {
getJobs();
addNameTextbox.value = '';
})
.catch(error => console.error('Unable to add job.', error));
}
Running the UI request to add job, now adds it without a trigger (to be worked on in separate section). To confirm, I then ran API request in browser to fetch all jobs for the running scheduler using:
[https://localhost:44379/api/schedulers/QuartzScheduler/jobs]
resulting in:
[{"name":"HelloWorldJob","group":"DEFAULT"},{"name":"TestJob","group":"DEFAULT"}]
That implies a few things:
Passing JSON object in body does not associate it with API function parameters. I need to add all parameters in url string to use them. May be there is a way to use body parameters.
Now that the class is correctly referenced in API, I can continue passing just the class name through UI, without namespace and assembly to keep it secure as class is defined in the project at build time.
Adding Console.Writeline in API function did not return any output at runtime.

Postman parsing data into excel

The code I wrote is having a single error(that I know of). That error being:
line 44, in
Match_Address1= store["addressLine1"]
KeyError: 'addressLine1'
The goal of the code is to scrape Mcdonalds website and grab location information and phone number to put into excel. This is so I can track closures and location changes to a previous list.I used postman to help set up a payload, etc to get the information.I know that I am getting all the information back(address,phone and more) from the link but parsing it somehow is being trickier than I thought. If anyone can point me in the right direction that be great!
My guess is that I am not going into 'features' properly to the subsection called properties where the information I want is located. However that is just my guess.
Also, if it helps I can post the original code that just prints all the information.
Thanks in advance

How is this site forming the headers on a POST request?

I am trying to learn how the headers are being constructed when a zipcode is entered by the user and a "POST" command is issued (by clicking on the "Shop Now" button) from the following website:
I believe the interesting part of this "POST" request is how the site is forming the following headers but I can't figure out how it is doing it (my suspicion is that there is some JavaScript/Angular code that is responsible):
x-ccwfdfx7-a
x-ccwfdfx7-b
x-ccwfdfx7-c
x-ccwfdfx7-d
x-ccwfdfx7-f
x-ccwfdfx7-z
So I have tried to use the requests module to login as guest to learn more about how this flow works:
with requests.Session()
with cloudscraper.create_scraper()
So far all my attempts have FAILED. Here is my code:
import requests
from requests_toolbelt.utils import dump #pip install requests_toolbelt
import cloudscraper #pip install cloudscraper
#with requests.Session() as session:
with cloudscraper.create_scraper(
browser={
'custom': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36'
}
) as session:
CITY = XXXXX
ZIPCODE = XXXXX
#get cookies
url = 'http://www.peapod.com'
res1 = session.get(url)
session.headers['Referer'] = 'https://www.peapod.com/'
#get more cookies
url = 'http://www.peapod.com/login'
res2 = session.get(url)
#get more cookies
url = 'https://www.peapod.com/ppd/bundles/js/ppdBundle.js'
res3 = session.get(url)
#get all the service locations
response = session.get('https://www.peapod.com/api/v4.0/serviceLocations',
params={
'customerType': 'C',
'zip': ZIPCODE
}
)
try:
loc_id = list(
filter(
lambda x: x.get('location', {}).get('city') == CITY, response.json()['response']['locations']
)
)[0]['location']['id']
except IndexError:
raise ValueError("Can't find City '{}' -> Zip {}".format(CITY, ZIPCODE))
#login as guest
response = session.post('https://www.peapod.com/api/v4.0/user/guest',
json={
'customerType': 'C',
'cities': None,
'email': None,
'serviceLocationId': loc_id,
'zip': ZIPCODE
},
params={
'serviceLocationId': loc_id,
'zip': ZIPCODE
}
)
This seems to produce some sort of an error message saying "I'm blocked" which I believe is due to the fact that I can't figure out how the browser constructs the ccwfdfx7headers in the "POST" request (my suspicion is that there is some JavaScript/Angular code that is responsible for constructing these headers but I can't find it and hoping someone could help...)
On the same computer, Chrome browser is able to login just fine

Log into JavaScript login form requests

I am trying to log into this website that uses a JS based form. Is this even possible with the Python requests library?
payload = {
'_username': 'xxx#xxx.com',
'_password': 'xxx',
'_remember_me': 'false'
}
with requests.Session() as s:
p = s.post('https://www.lovoo.com/login_check', data=payload)
r = s.get('https://www.lovoo.com/list/visits')
print(r.text)
I search r.text afterwards with grep, but I see I am still not logged in?

You need to do an initial get to set some cookies and add some headers:
head = {
"User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36",
"X-Requested-With": "XMLHttpRequest",
}
with requests.Session() as s:
s.get("https://www.lovoo.com")
p = s.post('https://www.lovoo.com/login_check', data=payload, headers=head)
r = s.get('https://www.lovoo.com/list/visits')
If you print p.json() you will see a response like {"referer":"https:\/\/www.lovoo.com\/welcome\/login","success":true,"user":{}} which means you have successfully logged in.

For some reason the website does not like your user agent. Remove the user agent header and it will work.
