Summary
The handling added in #40515 broke the handling for
fileIdsthat don't exist anywhere.Notes
One difference in behavior remains (versus <NC28) and that is that when we redirect to the
index, the URL in the browser used to drop the bogus fileId (but now it stays). I'd personally would prefer to drop it. I haven't deciphered all the changes to the newerfilesto know where that's coming from. I tried using the old RedirectResponse approach taken in NC27 (see here) and the bogus fileId still sticks around now. Open to suggestions and/or ignoring it since it may be outside the scope of this PR.Backport only to v28
