So, on my windows machine I defined an environment variable like
SET VUE_MAP_PORTAL_TITLE=Map
And in my Vue application I try to use it in this way:
<v-input hide-details clearable>{{process.env.VUE_MAP_PORTAL_TITLE}}</v-input>
However, when I run my application, I get this error message in the console:
TypeError: "e.process is undefined"
And in debug tools, I see that in fact this construct is undefined: _vm.process
So, what is wrong with that ans how can I fix it. By the way, in .env file this variable is also defined.

I am trying to create a web application that mimics trello. I keep getting this error and im not sure how to fix it. The code works fine in another project but not when i try and add it to this new project. ALL dependencies are updated. I am running it on google chrome. I read it might be a problem with chrome?
This is the error that I am receiving on my browser. There are no errors in my IDE.
This is the code that is producing this error. The code works fine in another IDE but once I try to integrate the component into my new app it crashes.
Make sure you are getting array in list key in "board" Props and try to use optional Channing
{
boar?.list?.map(..)
}
Your board props is undefined that's why you're getting this error.
As described above, I am getting an error and an empty page (but the layout including the navbar is there) is shown. This error always occurs, when I refresh the link via the browser or in case I access the link directly through the browser. Everything is fine, when I use my navigation bar to navigate through the templates. So, I can´t see any data after a real "load" of the page.
I am using Meteor Blaze on Windows.
Here is a screenshot:
Neither the picture, nor other data is shown.
I am not sure, if this is 100% the reason for that behavior, but always if this behavior occurs, I get this error message in the client console:

I searched for tracker, afterFlush etc., but I am not sure what I have to change in my code?
When you load this route "fresh" (using a refresh or pasting the url into the browser) Meteor reloads the entire application including the Meteor.user() object. At line 40 of client/templates/common/navigation.js you are probably trying to access Meteor.user().username but Meteor.user() hasn't yet loaded so you get the error. You need to defend against this in your code and/or show a loading template until your subscriptions and the user object are all ready.
The first line of the error dump points to the error:
TypeError: Cannot read property 'username' of undefined at Blaze.TemplateInstance.
(http://localhost:3000/app/client/templates/common/navigation.js?hash=142e989d312ba94a4b875a71e5e557bdd5255272:3:40)
The :40 at the end there is the line number the error occurred on.
I get the following error:
0x800a138f - JavaScript runtime error: Unable to get property 'activate' of undefined or null reference
when running the following line of javascript in my UWP App:
Windows.UI.Xaml.Window.activate();
Windows.UI.Xaml.Window.current.activate();
or
Windows.UI.Core.CoreWindow.activate();
API Reference, Handle app activation Doc
Windows.Ui.Xaml and the docs you linked aren't relevant for HTML/JavaScript apps. Windows.UI.Xaml is used only in Xaml apps.
To call activate You need a Windows.UI.Core.CoreWindow object, but Windows.UI.Core.CoreWindow itself is logically a class not an object
You need to create or acquire an instance of the class to call activate. To get such an object call CoreWindow's static method getForCurrentThread
var window = Windows.UI.Core.CoreWindow.getForCurrentThread();
Window.activate();
That said, what problem are you actually trying to solve? Why are you calling this? Initial window activation in JavaScript apps is handled by framework code not called explicitly by app code. Unless you're managing multiple CoreWindows in your app, attempts to activate the window will depend on it already being active: you can't force your window on the user.
On my computer it's work well. After deploying on meteor.com I get error.
Creating collection look like this ( /lib/collections/messages.js )
Messages = new Meteor.Collection('messages');
On browser console after input
Messages.insert({})
I get
Uncaught ReferenceError: Messages is not defined
Its very likely you have a syntax error somewhere in your code.
If you check up your browser console the syntax error is visible.
On your localhost the files are not concatenated into one single js file, so if there is an error somewhere, then the issue isn't too bad & your app will run fine, mostly.
The thing is when your entire project is concatenated into one single js file then when there is an error higher up in your code, the downstream code will not execute. So the code at /lib/collections/messages.js does not run & this is why it is not defined.
The error is likely to be something like cannot read null of undefined or uncaught reference error or something like that. If you solve whatever is causing this error and redeploy your app.
I upgraded to ios5 and my little app o longer works. I am getting a really nebulous error
JavaScript error undefined type error 'undefined' is not an object
The problem is, I don't have a variable called undefined.
I am also getting a cache manifest error
Application cach manifest has an incorrect Mime type image/png
Which I believe is a result of my script converting an svg canvas to a png (it worked in its 4). Any help with this weird, nebulous undefined error would help. I tried using alerts to try and see what variable is being declared undefined, but the error simply states undefined is not an object and gives no variable name or even what line of code the error appears on.
Code below

You can view it here lesserslavery.org/ice.html
The undefined-error means you are trying to access a variable in an object way, even though the object is not defined. Probably you are assuming somewhere that certain element was assigned for the variable, which it wasn't.
For the mime type question, your server probably is sending wrong mime type with the file defined in cache.manifest. Check possible explanation here: Debugging html5 offline web apps
