HTML build fails with jinja2 warning

[tbirdso]

Raw build log from docs CI shows notebook failure:

2022-03-24T21:34:18.3376638Z Notebook error:

CDash reports 1 compiler warning but seems to not report the trace above.

Unclear on the underlying cause as I'm not aware of any recent modifications to the notebook or build system.

Looks like an issue in jinja2 / nbconvert:

jupyter/nbconvert#1736

See that discussion for version workarounds.

Looks like jinja issue is resolved, seeing what appears to be an issue with the Fleek API key for deployment:

I stand corrected, the deploy issue in the main branch is here:
