Gitlab mirror broken for snowflake-webext

I just pushed some new commits to the snowflake-webext gitweb.tp.o repo: https://gitweb.torproject.org/pluggable-transports/snowflake-webext.git/log/

But they aren't being properly mirrored to the gitlab repository: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake-webext/-/commits/master

I got the following error message during the push:

$ git push origin master
