AttributeError: 'dict' object has no attribute 'version_type' when trying to use git_client.get_commits search_criteria

[SCMSADMIN]

When trying to get all the commits on a branch I get an attribute error.

Code:
from azure.devops.connection import Connection
from azure.devops.v7_0.git import GitClient
from azure.devops.v7_0.git.models import GitQueryCommitsCriteria
from msrest.authentication import BasicAuthentication

cm_search_criteria = GitQueryCommitsCriteria(
item_version={"version": branch_name,"versionType": 'branch'}
)

        print (f"search critera")
        print (cm_search_criteria)
        print (f"search critera")
        
        commits = git_client.get_commits(
            repo_name,
            project=project_name,
            search_criteria=cm_search_criteria
        )    

Results:
Traceback (most recent call last):
File "C:\PythonWork\Tool Connectivity\ADO_ALL_REPOS_BRANCHES_COMMITS.py", line 66, in
commits = git_client.get_commits(
repo_name,

if search_criteria.item_version.version_type is not None:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'dict' object has no attribute 'version_type'

I cannot see anything wrong with the code, but it is throwing an error, does any one see an error?

Did a little investigating on the issue and added some print statements to git_client_base.py to see what might be going on,

The area of git_client_base.py I added the print statements is
##################################################################################################
print (f"SEARCH CRITERIA->> {search_criteria}\n") ### REMOVE
print (f"Before {search_criteria.item_version}") ### REMOVE
if search_criteria.item_version is not None:
print (f"After {search_criteria.item_version}") ### REMOVE
print (search_criteria.item_version) ### REMOVE
print (search_criteria.item_version.versionType) ### REMOVE
if search_criteria.item_version.versionType is not None:
print (f"POST {search_criteria.item_version}") ### REMOVE
query_parameters['searchCriteria.itemVersion.versionType'] = search_criteria.item_version.versionType
if search_criteria.item_version.version is not None:
query_parameters['searchCriteria.itemVersion.version'] = search_criteria.item_version.version
if search_criteria.item_version.version_options is not None:
query_parameters['searchCriteria.itemVersion.versionOptions'] = search_criteria.item_version.version_options
##################################################################################################
And the output is
SEARCH CRITERIA->> {'additional_properties': {}, 'skip': None, 'top': None, 'author': None, 'compare_version': None, 'exclude_deletes': None, 'from_commit_id': None, 'from_date': None, 'history_mode': None, 'ids': None, 'include_links': None, 'include_push_data': None, 'include_user_image_url': None, 'include_work_items': None, 'item_path': None, 'item_version': {'versionType': 'branch', 'version': 'CORE-OSB'}, 'show_oldest_commits_first': None, 'to_commit_id': None, 'to_date': None, 'user': None}

Before {'versionType': 'branch', 'version': 'CORE-OSB'}
After {'versionType': 'branch', 'version': 'CORE-OSB'}
{'versionType': 'branch', 'version': 'CORE-OSB'}

AttributeError: 'dict' object has no attribute 'versionType'

From what I can see the error "AttributeError: 'dict' object has no attribute 'versionType'" is because looking at my printstatements

search_criteria.item_version can easily be seen and show versionType is there but the attributes version or versionType cannot be expanded to a third dictionary position (search_criteria.compare_version.version_type or version.

To the program search_criteria.item_version.versionType does not exist as it appears blank.

This is definitely an API issue.
