Noticed in the issue there was a user where the response had
###!/usr/bin/env php in the beginning for some reason. It won't fix the actual issue but figured it's quick to handle it in case others have this issue too.
Looks like a test is failing now.
Closing this for now as I think it won't fix the issue anyway. Could otherwise rewrite that logic but thinking it might not be needed and I don't want to do too many string operations there on all the archive responses. To be seen. Will recreate if needed.
