@MV88 there is a failing test which is not depending on this PR. @offtherailz will check it during review.

Instead of using the first URL, An error should be shown because the format with array is not supported, and so it is error prone.

Please show misconfiguration error.

The catalog still works for some reason in search, while gives error in the editor, as expected
even if not properly consistent, I think that it is enough for a misconfiguration, that by definition can have inconsistent results.
