This may looks like a valid error, but there is no indication whatsoever on how to fix it

Can you enable debug log level (log_level = 0) and check for log messaged for app = objectstore ?

joshtrichards · 2025-03-02T14:58:13Z

Are you certain there isn't a space at the end of the bucket name or something?

Check by running occ files_external:list --output=json_pretty maybe?

Thats also my guess (and why I asked for the log)

Retidurc · 2025-03-02T18:13:12Z

There was indeed a whitespace, but in the beginning of both the bucket name, and the domain name.
Trailing whitespaces where what I double checked first. And due to the wording of the error I was thinking about something more technical as the cause .

Should I mark this as resolved? Technically not a bug, but I think maaaaybe the error messages need to be a bit more explicit about leading or trailing whitespaces, just to not mislead about the real issue.

I agree.

Not everyone knows the acceptable characters for DNS hostnames off the top of their head. ;-)

And "DNS compatible" may be a bit too vague.

As for spaces, we could trim them I think safely automatically. We do that in many other places already.
