4 years ago Happens during group creation. Click on + button to add a group, fill in a title and a name for the first member to get the checkmark to stop greying out, then add another member
This is apparently a very bad error that happens in various places around our app which I currently forget. Explore and try to get it to trigger, then fix it. Keep the browser developer tools open to see the error (on Firefox, this might catch you off guard as it triggers the debugger in my case). The website is still functional when this error happens, but it indicates a problem with our Angular code.
