When I try leaving a comment on the 0 line I get this error:

Error: Error during POST: Status code: 422 Unprocessable Entity, Body: {"message":"Unprocessable Entity","errors":["Pull request review thread line required and an integer greater than zero and Pull request review thread diff hunk can't be blank"],"documentation_url":"https://docs.github.com/rest/reference/pulls#create-a-review-for-a-pull-request"}

which is different than your error.

Maybe GH has limitations on which files can be commented on? eg for too large of diffs? Not sure
