admin panel stuck within login screen

[wennemer]

Describe the bug

Hi,
We have deployed unleash 5.12.2 with helm chart 4.1.1 within our kubernetes cluster including an ingress service:

• Our react frontend can connect to the server and is 100% functional.
• The admin panel can be reached directly by portforwarding from the cluster and is 100% functional

--

• The admin panel can not be reached by the subdomain https://unleash.domain.com:

• The login page stuck in loading state showing the spinner.

• There are no errors within the developer tools using edge or chrome browser

• Firefox maybe gives us a hint:

Source-Map-Fehler: Error: JSON.parse: unexpected character at line 1 column 1 of the JSON data

The source files may not be accessible.

Are the json files or the json map files to be read available? May we verify their paths (locations) for reading them?

We find a solution:
We normally use custom error pages in our nginx service.
I think the admin ui needs the error pages of the unleash server instead of our owns.
After removing these regarding the unleash server, everything is fine.

Thanks!
