pushing with jj returns: unexpected status code: 404 #124

I have a repo on tangled that I push to with jj. Every push ends with the line: remote: time=2025-06-07T11:00:09.042Z level=ERROR msg="unexpected status code: 404". Despite the errorl, as far as I can tell, the push succeeds` Since this is from the remote, I assume it's an issue with tangled.

$ jj version
jj 0.30.0

$ jj git push --debug --remote=tangled -b master
2025-06-07T11:00:08.314799Z  INFO jj_cli::cli_util: debug logging enabled
