This sample shows how to use an interceptor to propagate contextual information through workflows and activities. For this example, contextvars holds the contextual information.
To run, first see README.md for prerequisites. Then, run the following from this directory to start the worker:
poetry run python worker.py
This will start the worker. Then, in another terminal, run the following to execute the workflow:
poetry run python starter.py
The starter terminal should complete with the hello result and the worker terminal should show the logs with the propagated user ID contextual information flowing through the workflows/activities.
