Are you on Panel master? I cannot reproduce.

[hoxbro]

Yes. Both on panel and lumen.

[philippjfr]

You'll have to fetch the latest resources by rerunning an editable install on Panel.

[philippjfr]

Alternatively you can also just run panel.compiler.bundle_resources()

[hoxbro]

It works now.

I needed to run python setup.py develop. python -m pip install --no-build-isolation --no-deps -e . was not enough.

[philippjfr]

python -m pip install --no-build-isolation --no-deps -e . was not enough.

Probably due to latest pip nonsense. Setting this probably would have done it:

SETUPTOOLS_ENABLE_FEATURES: "legacy-editable"

Just found that https://github.com/holoviz/panel/blob/bdf2742679fb16861b8432872aadb0ed3baddda7/panel/_templates/index.html still using the CDN from https://cdn.holoviz.org/panel/latest/dist/bundled/js/, instead of https://cdn.jsdelivr.net/npm.

[philippjfr]

cdn.holoviz.org is what it should be using.

[philippjfr]

Neither unpkg nor jsdelivr are recommended for production usage so we decided to maintain our own CDN.
