What changed?
Added
WORKFLOW_TASK_FAILED_CAUSE_REQUEST_TOO_LARGEto the workflow task failed cause enum. AddedNamespaceInfo.Limits.workflow_task_completion_size_limit_errorto communicate the server-enforced max RespondWorkflowTaskCompleted request size via DescribeNamespace.Why?
When a workflow task completion exceeds the server's size limit we currently fail with the generic
PAYLOADS_TOO_LARGE, which is misleading (no single payload is oversized). The new cause names the actual condition, and exposing the limit lets SDKs stay under it instead of discovering it by failing.Breaking changes
None. Additive-only
