Enumeration: WorkflowTaskFailedCause

enums.v1.WorkflowTaskFailedCause

Workflow tasks can fail for various reasons. Note that some of these reasons can only originate from the server, and some of them can only originate from the SDK/worker.

WORKFLOW_TASK_FAILED_CAUSE_FAILOVER_CLOSE_COMMAND value

WORKFLOW_TASK_FAILED_CAUSE_FEATURE_DISABLED​

• WORKFLOW_TASK_FAILED_CAUSE_FEATURE_DISABLED = 35

A workflow task completed requesting a feature that's disabled on the server (either system wide or - typically - for the workflow's namespace). Check the workflow task failure message for more information.

WORKFLOW_TASK_FAILED_CAUSE_FORCE_CLOSE_COMMAND​

• WORKFLOW_TASK_FAILED_CAUSE_FORCE_CLOSE_COMMAND = 17

WORKFLOW_TASK_FAILED_CAUSE_FORCE_CLOSE_COMMAND value

WORKFLOW_TASK_FAILED_CAUSE_GRPC_MESSAGE_TOO_LARGE​

• WORKFLOW_TASK_FAILED_CAUSE_GRPC_MESSAGE_TOO_LARGE = 36

A workflow task failed because a grpc message was too large.

WORKFLOW_TASK_FAILED_CAUSE_NON_DETERMINISTIC_ERROR​

• WORKFLOW_TASK_FAILED_CAUSE_NON_DETERMINISTIC_ERROR = 24

The worker encountered a mismatch while replaying history between what was expected, and what the workflow code actually did.

WORKFLOW_TASK_FAILED_CAUSE_PAYLOADS_TOO_LARGE​

• WORKFLOW_TASK_FAILED_CAUSE_PAYLOADS_TOO_LARGE = 37

A workflow task failed because payloads were too large.

WORKFLOW_TASK_FAILED_CAUSE_PENDING_ACTIVITIES_LIMIT_EXCEEDED​

• WORKFLOW_TASK_FAILED_CAUSE_PENDING_ACTIVITIES_LIMIT_EXCEEDED = 27

Starting a new activity would cause this workflow to exceed its limit of pending activities that we track.

WORKFLOW_TASK_FAILED_CAUSE_PENDING_CHILD_WORKFLOWS_LIMIT_EXCEEDED​

• WORKFLOW_TASK_FAILED_CAUSE_PENDING_CHILD_WORKFLOWS_LIMIT_EXCEEDED = 26

We send the below error codes to users when their requests would violate a size constraint of their workflow. We do this to ensure that the state of their workflow does not become too large because that can cause severe performance degradation. You can modify the thresholds for each of these errors within your dynamic config.

Spawning a new child workflow would cause this workflow to exceed its limit of pending child workflows.

WORKFLOW_TASK_FAILED_CAUSE_PENDING_NEXUS_OPERATIONS_LIMIT_EXCEEDED​

• WORKFLOW_TASK_FAILED_CAUSE_PENDING_NEXUS_OPERATIONS_LIMIT_EXCEEDED = 33

A workflow task completed requesting to schedule a Nexus Operation exceeding the server configured limit.

WORKFLOW_TASK_FAILED_CAUSE_PENDING_REQUEST_CANCEL_LIMIT_EXCEEDED​

• WORKFLOW_TASK_FAILED_CAUSE_PENDING_REQUEST_CANCEL_LIMIT_EXCEEDED = 29

Similarly, we have a buffer of pending requests to cancel other workflows. We return this error when our capacity for pending cancel requests is already reached.

WORKFLOW_TASK_FAILED_CAUSE_PENDING_SIGNALS_LIMIT_EXCEEDED​

• WORKFLOW_TASK_FAILED_CAUSE_PENDING_SIGNALS_LIMIT_EXCEEDED = 28

A workflow has a buffer of signals that have not yet reached their destination. We return this error when sending a new signal would exceed the capacity of this buffer.

WORKFLOW_TASK_FAILED_CAUSE_REQUEST_TOO_LARGE​

• WORKFLOW_TASK_FAILED_CAUSE_REQUEST_TOO_LARGE = 40

A workflow task failed because the request exceeded a size limit.

WORKFLOW_TASK_FAILED_CAUSE_RESET_STICKY_TASK_QUEUE​

• WORKFLOW_TASK_FAILED_CAUSE_RESET_STICKY_TASK_QUEUE = 13

The worker wishes to fail the task and have the next one be generated on a normal, not sticky queue. Generally workers should prefer to use the explicit ResetStickyTaskQueue RPC call.

WORKFLOW_TASK_FAILED_CAUSE_RESET_WORKFLOW​

• WORKFLOW_TASK_FAILED_CAUSE_RESET_WORKFLOW = 20

WORKFLOW_TASK_FAILED_CAUSE_RESET_WORKFLOW value

WORKFLOW_TASK_FAILED_CAUSE_SCHEDULE_ACTIVITY_DUPLICATE_ID​

• WORKFLOW_TASK_FAILED_CAUSE_SCHEDULE_ACTIVITY_DUPLICATE_ID = 22

WORKFLOW_TASK_FAILED_CAUSE_SCHEDULE_ACTIVITY_DUPLICATE_ID value

WORKFLOW_TASK_FAILED_CAUSE_START_TIMER_DUPLICATE_ID​

• WORKFLOW_TASK_FAILED_CAUSE_START_TIMER_DUPLICATE_ID = 12

WORKFLOW_TASK_FAILED_CAUSE_START_TIMER_DUPLICATE_ID value

WORKFLOW_TASK_FAILED_CAUSE_UNHANDLED_COMMAND​

• WORKFLOW_TASK_FAILED_CAUSE_UNHANDLED_COMMAND = 1

Between starting and completing the workflow task (with a workflow completion command), some new command (like a signal) was processed into workflow history. The outstanding task will be failed with this reason, and a worker must pick up a new task.

WORKFLOW_TASK_FAILED_CAUSE_UNHANDLED_UPDATE​

• WORKFLOW_TASK_FAILED_CAUSE_UNHANDLED_UPDATE = 31

Similar to WORKFLOW_TASK_FAILED_CAUSE_UNHANDLED_COMMAND, but for updates.

WORKFLOW_TASK_FAILED_CAUSE_UNSPECIFIED​

• WORKFLOW_TASK_FAILED_CAUSE_UNSPECIFIED = 0

WORKFLOW_TASK_FAILED_CAUSE_UNSPECIFIED value

WORKFLOW_TASK_FAILED_CAUSE_WORKFLOW_PAUSE_REQUESTED_BEFORE_TASK_STARTED​

• WORKFLOW_TASK_FAILED_CAUSE_WORKFLOW_PAUSE_REQUESTED_BEFORE_TASK_STARTED = 39

A workflow task is failed because the workflow is paused before the task is started.

WORKFLOW_TASK_FAILED_CAUSE_WORKFLOW_WORKER_UNHANDLED_FAILURE​

• WORKFLOW_TASK_FAILED_CAUSE_WORKFLOW_WORKER_UNHANDLED_FAILURE = 14

WORKFLOW_TASK_FAILED_CAUSE_WORKFLOW_WORKER_UNHANDLED_FAILURE value
