Atlassian-python-api Bitbucket functions

Agenda 1)
Refer: https://github.com/atlassian-api/atlassian-python-api/blob/master/atlassian/bitbucket.py
Some functions seems to not work, viz. get_pull_requests_contain_commit(project, repository, commit).
Same for the corresponding REST API
rest/api/1.0/projects/{project}/repos/{repository}/commits/{commitId}/pull-requests
Please share pointers here.

Agenda 2)
How to get a list of files affected in a pull request commit using Atlassian-python-api for Bitbucket?
