06/07/2022, 3:53 AMHi all, Is there any reason why a task runs regardless of the case result? I want to run a task only when a parameter is set to True. Implemented this using the Case control flow, but it runs irrespective of the case result. That is even when the parameter is set to False.

Can you show me a code sample?

param_flow_compute_bot_markers_enabled = Parameter(
"Run Compute Bots Markers", default=True
)
with case(param_flow_compute_bot_markers_enabled, True):
<http://logger.info|logger.info>(f"The flow {flow.name} is enabled")
registered_bots = _utils.get_configured_bots()I want to execute certain statements only when param_flow_compute_bot_markers_enabled is True

This looks right. Maybe you can register and show the schematic?

with case(param_flow_compute_bot_markers_enabled, False):
<http://logger.info|logger.info>(f"The flow {flow.name} is disabled. Skipping flow")
with case(param_flow_compute_bot_markers_enabled, True):
<http://logger.info|logger.info>(f"The flow {flow.name} is enabled")I could see both the the log messages with the above example.

That’s because the logger is evaluated during Flow creation time. It’s not deferred because it’s not in a task
