On a self hosted gitlab instance, I have a strange problem and no clue to fix it.
MR are enabled on the projects, the API behaves normally, but the view in the app always returns 404.
- Project preferences in the app show MR are enabled
- Project attributes in the API show the same info
- Calling the API with curl and a Private token is ok
- Webview shows a 404 error page
- the developer console displays no error at all, and network monitor simply shows the 404
- production logs show nothing, just one line about the 404 status but no reason given
- all the rake tasks I tried give me a valid status, and still no clue
It is the only view that give such outputs, the personal MR pages and group MR pages are looking good.
Does anyone have an idea on what is going wrong?
