When I manually try to start dash_app, I get what appears to be a python syntax error, preceded by numerous deprecation warnings. The dash app never appears on my web browser. I've updated and pulled everything.

Help! Raspberry 4 B running Bullseye, connecting to the router via ethernet (not WiFi).

Could you do this instead and print out the results?

cd dash_app
sudo python3 index.py

Note: We have NOT Tested Bullseye and it is not supported at this time. We will support it when we product our V19 SD Card (March or April).

We know Bullseye has problems with the PiCamera but they are getting cleaned up.

It would be best if you pip installed an older version of Dash as well. Thanks, Jason

Did you do something different? BP

There are a lot of syntactical changes in that version that differ from previous 1.x versions. Thanks, Jason

Thank you. We haven't tried 2.0 yet. Needs to get on the list. BP

Thanks, Jason

See what Jason has said above. BP
