Problem deploying with Pipelines - Auth 500 error on git clone

I'm having problems with pipelines and it seems to be related to an issue from yesterday (BCLOUD-14039). Here's the output, of the very first step:

GIT_LFS_SKIP_SMUDGE=1 git clone --branch="feature/docker-pipelines" --depth 50 https://x-token-auth:$REPOSITORY_OAUTH_ACCESS_TOKEN@bitbucket.org/xxx/yyy.git $BUILD_DIR ; git reset --hard 3fd2599c6720f0c10207a50f0c67586b2aa7c9e4 ; git remote set-url origin git@bitbucket.org:xxx/yyy.git Cloning into '/opt/atlassian/pipelines/agent/build'... remote: unable to authorize current user, internal server error fatal: unable to access 'https://x-token-auth:$REPOSITORY_OAUTH_ACCESS_TOKEN@bitbucket.org/xxx/yyy.git/': The requested URL returned error: 500
