I am trying to create a python project that creates multiple PR requests for a single branch but get the error.” HTTPError(‘Branch “” is already up-to-date with branch “” in repository “”.’)

from atlassian import Bitbucket  
      
for src_branch_name in src_branch_list 
       response = bitbucket.open_pull_request(project, repo_name, project, repo_name, src_branch_name, dest_branch_name, title, description,reviewers)
