CHW-5501 UsageStoreFailure
usage / billing store write failed; retry shortly and contact support if the failure persists
Default message: usage / billing store write failed; retry shortly and contact support if the failure persists
HTTP status:500(server)
Problem. A usage / billing write (assign plan, create plan, update plan, update org_usage_limits) returned 500. Cause. The DB call failed for a non-conflict reason (connection lost, deadlock, schema drift). Fix. Retry shortly; if persistent, check the server logs for the underlying error and contact support. HTTP 500.
