Hello,
I’m trying to setup a temporal workflow using spring boot.
I’ve defined activities as beans, etc. Basically was following the examples from temporal git.

Workflow starts, but throws following errors in logs:

Any ideas what could go wrong?

Hi @Volodymyr_Konoval

Local Activity Worker is not started, no activities were registered

it seems the activity implementation is not registered to the worker

I’ve defined activities as beans, etc. Basically was following the examples from temporal git.

Can you check if you are either:
