Errors thrown by crate::Core::poll_workflow_task

Variants

WorkflowUpdateError

There was an error specific to a workflow instance. The cached workflow should be deleted from lang side.

Fields of WorkflowUpdateError

source: WorkflowError

Underlying workflow error

run_id: String

The run id of the erring workflow

BadPollResponseFromServer(PollWorkflowTaskQueueResponse)

The server returned a malformed polling response. Either we aren’t handling a valid form, or the server is bugging out. Likely fatal.

ShutDown

crate::Core::shutdown was called, and there are no more replay tasks to be handled. Lang must call crate::Core::complete_workflow_task for any remaining tasks, and then may exit.

TonicError(Status)

Unhandled error when calling the temporal server. Core will attempt to retry any non-fatal errors, so lang should consider this fatal.
