[Feature Request] Can we have more descriptive worker side error log?
Is your feature request related to a problem? Please describe.
While we changed the workflow/activity code and redeployed it, we expected the running workflow to use the new code. But instead, we faced a burst of the below message
2022-09-16T04:51:36.050908Z ERROR temporal_sdk_core::worker::workflow::managed_run: Error in run machines, error: RunUpdateErr { source: Nondeterminism("Complete workflow machine does not handle this event: HistoryEvent(id: 66, Some(ActivityTaskScheduled))"), complete_resp_chan: Some(Sender { inner: Some(Inner { state: State { is_complete: false, is_closed: false, is_rx_task_set: true, is_tx_task_set: false } }) }) }
I wanted to understand the log and make the following actions but we didn't have any additional log nor any hint from above log line about what to check. I wish the description of the error log from the worker side is more verbose.
Describe the solution you'd like
More descriptive error logs from worker side
Yes, this is a non-determinism issue. See https://docs.temporal.io/workflows (specifically https://docs.temporal.io/workflows/#code-changes-can-cause-non-deterministic-behavior).
I wish the description of the error log from the worker side is more verbose.
Any specific suggestions on what you would like to see here? Would a link to those docs be sufficient?
This error is written from our core engine, so I am transferring the issue there for some more discussion.
To clarify here, we need contextual state on our Core logs. We need workflow ID, run ID, workflow type, etc.
