Failed to authenticate SSH session: Waiting for USERAUTH response: GitError

[doapp-jeremy]

I created the stack with oauth key/secret for my bitbucket account. I webhook that calls the GitPullLambda runs when I push the code, however, I get this error:

Traceback (most recent call last):
File "/var/task/lambda_function.py", line 191, in lambda_handler
repo = create_repo(repo_path, remote_url, creds)
File "/var/task/lambda_function.py", line 69, in create_repo
repo = clone_repository(remote_url, repo_path, callbacks=creds)
File "/var/task/pygit2/__init__.py", line 263, in clone_repository
check_error(err)
File "/var/task/pygit2/errors.py", line 64, in check_error
raise GitError(message)
GitError: Failed to authenticate SSH session: Waiting for USERAUTH response

The key/secret for the Oauth consumer in my bitbucket account has read access to projects and repositories. Does it need more access?
