Duplicate of T220703: Increase the max length of URL to be shortened, I’d say – that URL is too long for w.wiki, yes.

I guess there could be a solution to this without needing to extend the limit of the URL shortener, so I wont merge it in as a dupe for now.

Possible solution could be for the UI to have a bit more functionality, and save the query essentially to a pastebin somewhere (or some storage) and then be able to retrieve it with a much shorter ID rather than the full query in the URL.
This might end up tying in with possible future query service UI work etc :)

Re. the "pastebin somewhere" idea: For our "SPARQL Lab", we use a mechanism to load queries from Github (or alternatively from an internal git repository). That has the additional advantage that the queries can be updated under a constant URL, discussed, forked etc. For details and links see https://zbw.eu/labs/en/blog/publishing-sparql-queries-live
