Cypress.io: Server Error | 404 - File or director not found

I'm currently trying to automate the test for a pretty big webapplication (DMS) Document Management System. To explain the system a little bit: There is a loadbalancer which connect to one of two frontends. To be sure that will be no problems in my test I directly try to access frontend one. Now to my problem:
When trying to run all the tests (around 20 spec-Files) with the Test Runner and also when trying to run the tests via console with the following command: .\node_modules\.bin\cypress run --spec "cypress/integration/Basis/**/*" --browser chrome
Sometimes after a cy.visit() a Server Error comes up. That error also stops the tests on console from running and looks like it crashes cypress. The error is the following:
It's not possible that the resource is missing or somewhere else because most of the times the test works. Most of the time its a different test where the error comes up. The worst part is that I have no idea how to reproduce that error. And it looks like that problem is only appearing for me.
So please tell me if you have ever seen this message and maybe you can help me fix this problem. Thank you for your help.

This is caused by a bug in Cypress which causes usages of window.location.href and other Location methods to incorrectly use /__/ as the base URL.
You can try enabling the experimentalSourceRewriting config option to work around this, read here for more info: https://docs.cypress.io/guides/references/experiments.html#Configuration

SMART on FHIR client-js: Invalid Character Error on IE11

Note: The issue is also reported on GitHub. Please take a look at Git issue as well for current progress/investigation.
I'm using fhir-client v0.1.15 to develop a SMART on FHIR web application that would run in EHR launch scenario. For example in Epic Hyperspace simulator that uses IE to run the SMART application.
While testing my application locally(localhost) on IE11, I get a JavaScript error from within fhir-client.js.
SCRIPT1014: Invalid character
File: fhir-client.js, Line: 38113, Column: 3
Below are the two lines from code. 38112 & 38113 in order:
var ret = Adapter.get().defer();
var state = JSON.parse(sessionStorage[params.state]);
Any solution or workaround would be much appreciated.
Updated
Upon further investigation we found that sessionStorage is empty when line with JSON.parse executes. However, strange thing is why/how sessionStorage gets empty after redirection from authorization server. This only happens with IE11, everything works fine on Chrome though.
PS. Can someone please add a new tag SMART or SMARTonFHIR?

Though I couldn't find the exact root cause and solution but let me share the findings that helped me resolve this issue somehow.
The issue doesn't exist when I test my SMART application with redirect_uri(in FHIR.oauth2.authorize call) set to a staging server URL instead of localhost.
PS. I’m open to better, and more qualified answers for acceptance.

Is there a --disable-web-security fix for recent changes of Chrome ~70?

I do cross-origin, cross-frame scripting in one of my projects (end to end testing with client side js without selenium) and that project highly relies on the --disable-web-security flag. From today one of my tests is failing. It tries to load a non-existent remote URI to a child window to check whether an error is thrown by the lib. Well I got an error, but that is a security error, so not what I expect. The other tests are between the karma server on localhost:9876 and a node server on localhost:4444. Those are working properly. My karma contains a Chrome custom launcher with the flag:
customLaunchers: {
"ch": {
"base": "Chrome",
"flags": ["--disable-web-security"]
}
},
As far as I know it needs some sort of user dir too, but the Karma launcher fills that param. Any idea about whether I can fix this or at least what release of Chrome changed the behavior? (I have already sent a bug report.)
Note that the question has nothing to do with Karma. All it does is starting Chrome from CLI with the given flags. A possible fix would be adding another flag, like the --user-data-dir was, but I guess the current changes are intentional and they cannot be undone. I'd like to see where this was discussed. I only found a 5 years old topic in Chromium Google Gorups which discusses this: https://groups.google.com/a/chromium.org/forum/#!msg/chromium-dev/iivpdszNY3I/3o3BF_mGwlIJ

Using --disable-site-isolation-trials is a partial solution. It works on https://www.google.com, but does not work on Chrome error pages with the error:// protocol.

JSCONSOLE does not work

I followed the instructions:( point browser to http://jsconsole.com, type :listen, got the descriptor, and put that little script into my web page...) ,but I only got the following output:
Creating connection...
Connected to ...
sent remote command
Nothing from the console.log got displayed.
I tried both edge and google chrome on my windows 10.I also tried to install a local version under node.js, but still no luck.
Not sure what's wrong, can somebody help? Thanks

How to Execute a Javascript in Internet Explorer from Command Line?

Recently at my job we have been wanting to automate our deployment process with new machines. I figured the best way to do this was by launching IE (since it's the default browser that's installed via Litetouch) via command line, which the generic code for it is as follows:
iexplore.exe http://reg.cmich.edu
Which works as expected; however the next part of the automation process is to pass IE at least a javascript file that can select the building I want to register a new NIC device at, then on the next pass I would pass it my administrative credentials.
For the most part, I can figure out by scrounging the net how to get Javascript to execute certain things in a browser like clicking links and entering text into text boxes. I'm just wondering if there's any way during running my batch script that I can pass IE a .js file to execute after the browser opens.
Any help would be greatly appreciated!

You can bypass IE completely by using cscript.exe to run JavaScript.
> cscript.exe "path/to/file.js"
cscript.exe is in c:\windows\system32.
Keep in mind that globals like window and document will not be available because you have no head.

Here you go enable by command
1) Go to Start -> Run
2) Type : CMD (then enter)
3) You will get command prompt window on screen.
4) Type below command and ten enter :
regsvr32 jscript.dll
5) Now check Internet Explorer. You will have javascript enabled.
Hope this would help you to solve your problem.
