Urgent: Unable to Modify App – "Cannot Read Properties of Undefined (Reading 'datasources')"

Hi everyone,

I've been working on a app for months, and last week everything was running smoothly with no major changes made. However, this week, I can't even load the app for editing—it crashes with the error:

"Cannot read properties of undefined (reading 'datasources')"

I'm stuck because I can’t modify or advance my project, and I have an important deadline coming up.

Here’s what I’ve tried so far:

Re-imported the app to see if that would fix the issue.
Cleared browser and environment caches.
Switched browsers and devices.

None of this worked...

Thanks in advance for the help !

PS: When clicking plus it's only the session ID

Hi

Can you try to re-store your app from a previous version. You can then restore your current version, but that's all I can think of aside from opening a Ticket
