Error 0x0 When Opening Form in New Tab

Applies to Product - Power Apps

What’s happening?
Form displays an error 0x0 when attempting to open in a new tab.
 

Reason:
This is caused by a conflict in the customer's custom JavaScript, specifically related to a function that is not executing properly.
 

Resolution:

1. Narrow down this by using the flag &flags=DisableFormHandlers=true to identify if the problem is related to the form handlers.
2. If the issue persists, test with additional flags:
3. &flags=DisableFormCommandbar=true
4. &flags=DisableFormLibraries=true
5. &flags=DisableWebResourceControls=true
6. If the error continues, export the unmanaged solution, modify the export XML to remove the problematic button, and then import the solution back.
7. Publish the app and check the command using the Command Checker tool.
