I’m unable to update any integrations. My setup works, but when I try to update, nothing happens.

The issue started when I updated to version 2026.4.2, so I downgraded to 2026.3.2, but the problem still persists.

I’ve tried several full reboots, but it hasn’t helped.

I don’t see any errors in the log files, but when I check the developer tools in my browser, I get this:

Any idea?
