OBSERVABILITY_STORAGE_GET_FEEDBACK_AGGREGATE_NOT_IMPLEMENTED

Error message

This storage provider does not support feedback aggregation

What it means

getFeedbackAggregate computes summary statistics over feedback records; the base observability storage class throws by default because aggregation is provider-specific. This error indicates the configured adapter does not implement feedback aggregation.

Solutions

1. Switch to a storage provider that implements feedback aggregation (libsql, postgres, upstash).
2. Implement getFeedbackAggregate in your adapter (COUNT/GROUP BY over feedback rows).
3. Catch the error and aggregate client-side from listFeedback results.
4. Upgrade the storage adapter package to match current core APIs.

Example fix

// before
const agg = await storage.getFeedbackAggregate({ scope }); // throws
// after
try {
  const agg = await storage.getFeedbackAggregate({ scope });
} catch (e) {
  if (e instanceof MastraError && e.id === 'OBSERVABILITY_STORAGE_GET_FEEDBACK_AGGREGATE_NOT_IMPLEMENTED') {
    return aggregateClientSide(await storage.listFeedback({ scope }));
  }
  throw e;
}

const supportsFeedbackAgg = storage.constructor.prototype.hasOwnProperty('getFeedbackAggregate');
if (!supportsFeedbackAgg) return aggregateClientSide(await safeListFeedback(storage, scope));

function hasFeedbackAggregate(s: any): s is { getFeedbackAggregate: (a: any) => Promise<any> } {
  return typeof s?.getFeedbackAggregate === 'function' && s.constructor.prototype.hasOwnProperty('getFeedbackAggregate');
}

try {
  return await storage.getFeedbackAggregate(args);
} catch (e) {
  if (e instanceof MastraError && e.id === 'OBSERVABILITY_STORAGE_GET_FEEDBACK_AGGREGATE_NOT_IMPLEMENTED') {
    return aggregateClientSide(await storage.listFeedback({ scope: args.scope }));
  }
  throw e;
}

When it happens

Trigger: Calling storage.getFeedbackAggregate({ scope, filters }) on an adapter extending the base without an override, or via analytics/UI requesting feedback summary metrics from a minimal provider.

Common situations: Custom storage backends implementing only trace persistence; feedback sentiment dashboards; adapter/core version mismatches.
