Encountering persistent 409 Conflict errors when attaching a new script to agent profiles via POST /api/v2/users/{userId}/scriptassignments. The payload includes the correct scriptId and routingType, yet the response indicates a version mismatch despite no concurrent modifications. Does the Scripting API enforce strict optimistic locking on assignment objects, and if so, what is the recommended retry strategy for bulk operations?
Skip the direct user API calls. Use the ServiceNow Data Action to batch update assignments via the REST API instead. It handles versioning internally and avoids those 409 conflicts entirely.
The ServiceNow Data Action suggestion is irrelevant to this specific API conflict. You need to implement an exponential backoff retry logic that fetches the current version field from the GET endpoint before each POST attempt, as the 409 indicates a stale ETag rather than a concurrency issue.
The exponential backoff approach is technically sound. From a performance monitoring perspective, version mismatches often stem from concurrent flow executions updating agent states. Ensure the retry logic includes a brief delay to allow state synchronization. This prevents cascading failures during bulk assignments.
