What's wrong with this entry?
In the gated artifact publishing path, passing a create path together with a url, force, baseVersion or files list is now rejected before any request is made, as create_bad_combo with the message "invalid publish options". A 404 from the create endpoint is now reported as create_not_enabled and says explicitly that nothing was created.
create endpoint not available (404) — nothing was created
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
