In GitLab, I can set up pushing to a remote repo, which I'd like to use for mirroring my GitLab project on Bitbucket. I set up 2 secret variables, BITBUCKET_USERNAME and BITBUCKET_PASSWORD w/ respective values. Then, under my GitLab project > Settings > Repository, I check "Remote mirror repository", set "Git Repository URL" to
https://$BITBUCKET_USERNAME:$BITBUCKET_PASSWORD@bitbucket.org/xxx/yyy.git,
uncheck "Only protected branches" and save the changes. Supposing I'm done, I hit the "Update now" button and get (after some time)
2:remote: Invalid username or password. If you log in via a third party service you must ensure you have an account password set in your account profile.
fatal: Authentication failed for '[FILTERED]@bitbucket.org/xxx/yyy.git/'
What am I doing wrong? The "ensure you have an account password set in your account profile" part is especially confusing (where else could one set it?).
EDIT: Investigated this a bit further. First, it seems you absolutely cannot set the password in your account profile, as it's now done over a web form. Second, resetting the Bitbucket password (and changing BITBUCKET_PASSWORD) didn't help. Third, unticking "Protected" next to BITBUCKET_PASSWORD and BITBUCKET_USERNAME also didn't help
