Nextcloud version is from the latest Docker image.
I’ve turned on logging and didn’t see anything so here’s a short explanation how to replicate it as I don’t have much more information other than this:
Go to users /settings/users, create a user with a username that matches this [0-9]+_[0-9]+, like for example 2_2.
You’ll notice the WebUI still works fine, however, when making an API request and setting the
OCS-APIRequest header to true, the response will be an empty (0 length) response with Status 200, OK
Is anyone else experiencing something similar?
I’ve tested both on my server and locally, I get the same thing…
