See https://en.wikipedia.org/w/index.php?title=User:Choi1997/UserProfileIntro&action=history Somehow the user created an empty page (I can't see any deleted edits), which shouldn't be possible. https://en.wikipedia.org/w/index.php?title=Special:Search&limit=500&offset=0&redirs=0&profile=all&search=UserProfileIntro shows a few more listed with 0 bytes.

Tested it myself: https://en.wikipedia.org/w/index.php?title=User:Legoktm/UserProfileIntro&action=history I went to https://en.m.wikipedia.org/wiki/Special:UserProfile/Legoktm, clicked the edit button, then hit submit without typing any text.

There is no prohibition against creating empty pages via the API. I guess if we want to avoid it in this case, we'll have to pass the existence of the page to the client and allow the JS to skip the save step in that case.
OK, I spoke to soon. We should not be able to create new empty pages through the API. I'm not sure what's going on here.
In my local instance, when I try to save an empty UserProfile, I get the following error from the API: "Creating new, empty pages is not allowed". On en.wiki, however, it works fine.
Submitted a patch set in gerrit, but for some reason it hasn't been added here: https://gerrit.wikimedia.org/r/#/c/99020/
