I'm running quarto on MacOS Monterey (12.1).
When issueing the render command I get the following error:
ERROR: TypeError: Cannot read properties of undefined (reading 'toLowerCase').

I've tried rendering from within VSCode and Jupyter Lab. Both give the same error message. 
No clue what causes this.
