getCasErrorCodeused a direct type assertion to detectIsOperationAborted(), which fails when the error is wrapped by memberlist'strySingleCas:This caused
ReplicasNotMatchError(normal HA deduplication) to be reported as status_code="500" incortex_kv_request_duration_secondswhen usingmemberlistas the HA tracker KV store, triggering false-positiveCortexKVStoreFailurealerts.Note: consul and etcd are unaffected because they return the callback error directly without wrapping (
return err), so the direct type assertion worked correctly for those backends.Which issue(s) this PR fixes:
