Hi
We started adding Replay tests based on the recommendation in the temporal docs. The replay tests seems to be failing for one of our Workflows throwing a NonDeterministicException.
The workflow is extremly simple , It reads the workflowID of the current workflow , appends child to it and creates a child workflow with that id . The Exception trace we get is listed below. Not sure if I am reading the trace properly but seems related to the workflow ID , We read the workflow id using “Workflow.getInfo().getWorkflowId()” is this allowed ? and does it work with WorkflowReplayer ?
> Unexpected exception thrown: java.lang.RuntimeException: query failure for workflow\_id: “workflow\_id\_in\_replay”
> run\_id: “run\_id\_in\_replay”
> , queryType=\_\_replay\_only, args=Optional.empty, error=io.temporal.worker.NonDeterministicException: Failure handling event 5 of type ‘EVENT\_TYPE\_START\_CHILD\_WORKFLOW\_EXECUTION\_INITIATED’ during replay. Command COMMAND\_TYPE\_START\_CHILD\_WORKFLOW\_EXECUTION doesn’t match event EVENT\_TYPE\_START\_CHILD\_WORKFLOW\_EXECUTION\_INITIATED with EventId=5 on check workflowId with an expected value ‘workflow\_id\_in\_replay-child’ and an actual value ‘MODIFY-SERVICE-watchdog-papillon-3eb7964c-fd3a-4335-8fc1-3d5b571081db-child’. {WorkflowTaskStartedEventId=9223372036854775807, CurrentStartedEventId=3}

Hi,
I think it is related to the child workflow ID; how are you generating it? Can you share the workflow history?
Try using Workflow.randomUUID or workflow.currentTimeMillis instead of libraries that generate non-determistic code.

Hi @antonio.perez
Here is a sample repo which replicates the error what @vjv is mentioning above. If you like, you can clone this repo. [GitHub - gauravojha/learningTemporal](https://github.com/gauravojha/learningTemporal/tree/master)
So what we are trying to do is
(Also mentioned here, hope this helps - [learningTemporal/src/main/java/dev/ojha/learningtemporal/workflows/HelloWorldWorkflowImpl.java at master · gauravojha/learningTemporal · GitHub](https://github.com/gauravojha/learningTemporal/blob/master/src/main/java/dev/ojha/learningtemporal/workflows/HelloWorldWorkflowImpl.java#L35-L40))
- Have a parent workflow trigger a child workflow
- What we are trying to do is, reusing the parent workflows ID (this we get by using the provided Temporal utility method - `Workflow.getInfo().getWorkflowId()`, and then using this is a prefix and just append “-child” to it. So for instance if the parent workflow ID is “helloWorld”, we are assigning our child workflow ID as “helloWorld-child”, as this simplifies some usecases of tracing and audit for our usecases
- When we do this, and replay the payload through the replay tests, we get an undeterministic error, I have attached the trace for this specific case at the end
- `Failure handling event 5 of type 'EVENT_TYPE_START_CHILD_WORKFLOW_EXECUTION_INITIATED' during replay. [TMPRL1100] Command COMMAND_TYPE_START_CHILD_WORKFLOW_EXECUTION doesn't match event EVENT_TYPE_START_CHILD_WORKFLOW_EXECUTION_INITIATED with EventId=5 on check workflowId with an expected value 'workflow_id_in_replay-child' and an actual value 'HelloWorldWorkflow-child'`
- However, if we don’t reuse the parent’s workflow ID, and let temporal use a random ID as the workflow ID of the child, then the replay tests pass.
The workflow history can be found here - [learningTemporal/src/test/resources/history\_failing.json at master · gauravojha/learningTemporal · GitHub](https://github.com/gauravojha/learningTemporal/blob/master/src/test/resources/history_failing.json)
Thank you for helping us on this. Let us know if you need more information.
Regards,
Gaurav

Posting the trace separately because of size limit
