Failed to resolve created workspace

Error message

Failed to resolve created workspace

What it means

After a successful create, the handler re-reads the record with workspaceStore.getByIdResolved(id) to return the thin record plus resolved version config; a null result triggers this 500. It signals that the write reported success but the read-back failed, i.e. a storage consistency or resolution problem.

Solutions

1. Verify the storage adapter implements getByIdResolved correctly and that create is synchronously durable before the read-back.
2. Check server logs for the wrapped 'Error creating stored workspace' handleError output to find the underlying store error.
3. Test the workspaces store directly (create then getByIdResolved) to isolate the storage layer.
4. Upgrade @mastra/core / storage packages to a version where the workspaces domain is fully implemented.

Example fix

// before (custom store)
async getByIdResolved(id) { return this.cache.get(id); } // cache may miss right after create
// after
async getByIdResolved(id) { return this.db.query('...').where({ id }); } // read from source of truth

const store = await storage.getStore('workspaces');
if (!store || typeof store.getByIdResolved !== 'function') throw new Error('Workspaces store unusable');

function hasResolvedReader(store): store is { getByIdResolved(id: string): Promise<unknown> } {
  return !!store && typeof (store as any).getByIdResolved === 'function';
}

try {
  await client.createWorkspace({ id, name });
} catch (e) {
  if (e.status === 500) {
    // read-back failure: poll briefly before giving up
    for (let i = 0; i < 3; i++) {
      const ws = await client.getWorkspace(id).catch(() => null);
      if (ws) return ws;
      await sleep(100);
    }
  }
  throw e;
}

When it happens

Trigger: workspaceStore.getByIdResolved(id) returns null/undefined immediately after workspaceStore.create(...) succeeded in the create handler.

Common situations: Eventual-consistency lag or caching in a custom storage adapter; the resolved view fails because referenced version config cannot be resolved; a buggy or partially implemented workspaces store.
