object of type 'VersionInfo' has no len()

[sagimann]

Hello, I'm new to sphinx multiversion. I tried to build using: sphinx-multiversion . public

and got:

Theme error:
An error happened in rendering the page docs/common_structures/MyStruct.
Reason: TypeError("object of type 'VersionInfo' has no len()")

I am using python3 venv and installed latest sphinx multiversion using pip. My conf.py has the following:

extensions = [
    'sphinx_rtd_theme',
...
    'sphinx_multiversion'
]

templates_path = ['_templates']

# SET CURRENT_VERSION
from git import Repo
repo = Repo( search_parent_directories=True )
current_version = repo.active_branch.name
html_context['current_version'] = current_version
html_context['version'] = current_version
html_context['versions'] = list()
versions = [branch.name for branch in repo.branches]
for version in versions:
    html_context['versions'].append( (version, f'/{VERSION_BASE_URI}/{version}/index.html') )
