DeprecationWarning: invalid escape sequence

For a while I've been seeing the following errors when checking my Home Assistant configuration or restarting the server – I've finally got around to tracing it down to the Office 365 custom_component.

The logs initially are riddled with deprecation warnings regarding lexer.py:

/home/administrator/.pyenv/versions/3.7.5/envs/homeassistant/lib/python3.7/site-packages/jinja2/lexer.py:648: DeprecationWarning: invalid escape sequence '\s'
  .decode("unicode-escape")
/home/administrator/.pyenv/versions/3.7.5/envs/homeassistant/lib/python3.7/site-packages/jinja2/lexer.py:648: DeprecationWarning: invalid escape sequence '\D'
  .decode("unicode-escape")
/home/administrator/.pyenv/versions/3.7.5/envs/homeassistant/lib/python3.7/site-packages/jinja2/lexer.py:648: DeprecationWarning: invalid escape sequence '\D'
  .decode("unicode-escape")
/home/administrator/.pyenv/versions/3.7.5/envs/homeassistant/lib/python3.7/site-packages/jinja2/lexer.py:648: DeprecationWarning: invalid escape sequence '\d'
  .decode("unicode-escape")

This has been for the past few versions of HA, but my current config is as follows:

• Home Assistant Core 0.115.2
• Python 3.7.5 (pyenv)
• HACS 1.6.0
• O365 2.1.8
