anvil.server.NoServerFunctionError No server function " 'matching "anvil.private.get_client_config" has been registered

For some reason i can’t add bug category
but i have
‘anvil.server.NoServerFunctionError’>: No server function matching “anvil.private.get_client_config” has been registered’
see the same issue here

we didn’t change anything in app

That’s by design. Anvil personnel will decide whether it’s an Anvil bug or not.

Just a wild shot here, but is it possible that you’re using an out-of-date anvil-uplink? See anvil-uplink · PyPI

Hi @anton.bogdanov - we weren’t able to reproduce this, so we might need a bit more information

Are you working with the open source app-server?
Could you provide the full code in the notebook?

(you can post the code as a private message if you wish,
if you post it publicly be sure to remove any uplink keys)
