When an action violates effective policy, APIs return 403 with payloads such as:
policy_violationpolicyKey(e.g.disableJsonExport,disablePlaygroundForRoles)- Human-readable
message
The UI component BlockedByPolicy surfaces these errors. Ask your admin which workspace role you have and whether org or workspace policy blocks the action.
Note: Some generation endpoints may not attach workspace context the same way as playground—if behavior differs, your admin should review policy matrix in engineering notes.
