Cryptic 400 when trying to close as duplicate of a Wiki
With my new moderator powers, I tried testing closing a question as a duplicate. I was able to close [In search of moderator powers](https://a.dev.codidact.org/posts/98) as a duplicate of [Formatting sandbox](https://a.dev.codidact.org/posts/103), which is in a different category, but before that I tried closing it as a duplicate of [Basic Wiki reading guidance](https://a.dev.codidact.org/posts/97), which is not a question (it's a Wiki). This failed, but instead of giving a message with a reason, it just displayed a pop up red box notice with "400" and nothing else.

Is this a problem with the dev server or a general problem to be raised on real Meta?
