Queries succeed against a running workflow, but are rejected while the workflow is paused. Unpausing makes it queryable again.

Workflow Pause is experimental. The dev server must be started with the pause flag enabled — see the workflow_pause README for prerequisites. First see the main README.md for general prerequisites.

Run the worker in one terminal:

uv run workflow_pause/queries/worker.py

Start the workflow in a second terminal:

uv run workflow_pause/queries/starter.py

Query it while running — this returns the current count:

temporal workflow query -w pause-queries-wf --type current_count

Pause it:

temporal workflow pause -w pause-queries-wf --reason demo

Query again — it is now rejected:

temporal workflow query -w pause-queries-wf --type current_count
# Error: query was rejected, workflow has status: Paused

Unpause it and the query works again:

temporal workflow unpause -w pause-queries-wf
temporal workflow query -w pause-queries-wf --type current_count
