Is the PR test script for zotero/translators repository still works?

For some reasons, we currently have to maintain some translators separately on l0o0/translators_CN. I use GitHub action script to automatically synchronize some practical files from zotero/translators monthly, including ci.yaml itself. It works well when I push directly to master branch, but PR testing always fails (e.g. #386). I have browsed the recent actions history of zotero/translators and found that PR tests in the official repository often fail as well.

Does the PR test script still make sense in practice? Do I need to make special settings for the repository (such as environment variables or something) to make it work properly?

The PR test script involves cloning the repository to the local. Since repository names are different, some additional processing needs to be done.
