Hello, It happened again and blocked CI for the Wikibase extension, so I disabled the test for now.

Hello @Ifrahkhanyaree_WMDE, two questions:
1- Do we want to add the site ID to the context (and the error message) for this error to point to which sitelink the user tried to modify its URL?
2- Do we want to return this error in the following case:

when replacing a sitelink that already exists, and providing a URL that is the same as the URL for the currently stored sitelink ( so do we ignore it since the URL is the same? or do we return the error anyway?).

In general, do we care about checking the stored URL for the sitelink? or do we just return this error as soon as we find the user added the URL in the request?
