SPO connection error "Unable to get property 'location' of undefined or null reference"

[buildbod]

I've shared my app with my organisation but several people are getting an error when they attempt to use it.

The app is connected to a SharePoint Online list.

Clicking on More reveals:

Unable to get property 'location' of undefined or null reference

How do I investigate what is going wrong?

Hi @buildbod,

Have you made sure that these users have the proper permission on this list?

Regards,

Yes. All users have permission. It's odd that it works for 80% of people.

I've also tried different browsers.

The errors messages include session id's. How can I use the ID to help with the investigation? How do I determine which 'location' is the source of the issue?
