I have some documentation deployed on readthedocs.io. It was working fine until I added the following line to my conf.py:
html_logo = '_static/logo.png',
As soon as I try to build the project on readthedocs it fails with the following error:
Running Sphinx v4.2.0
loading translations [en]... done

The above exception was the direct cause of the following exception:
