Failed to resolve updated workspace

Error message

Failed to resolve updated workspace

What it means

After applying workspaceStore.update(...), the handler re-reads via getByIdResolved(storedWorkspaceId) to return the updated resolved workspace; a null result triggers this 500. Like the create-path 500, it indicates the update reported success but the resolved read-back failed.

Solutions

1. Confirm update() persists durably and getByIdResolved can see it (no stale cache/read-replica lag).
2. Inspect handleError output ('Error updating stored workspace') for the root cause.
3. Test update-then-getByIdResolved directly against your storage adapter.
4. Upgrade storage/core packages to a fully implemented workspaces domain.

Example fix

// before
await store.update(input);
return store.cache.get(id); // stale cache -> null
// after
await store.update(input);
await store.cache.invalidate(id);
return store.getByIdResolved(id);

try {
  await client.updateWorkspace(id, patch);
} catch (e) {
  if (e.status === 500) {
    await sleep(150);
    const ws = await client.getWorkspace(id).catch(() => null);
    if (ws) return ws; // update likely landed despite read-back failure
  }
  throw e;
}

When it happens

Trigger: workspaceStore.getByIdResolved(id) returns null right after a successful update in the update handler — typically a storage adapter consistency or resolution failure.

Common situations: Custom/buggy storage adapter whose update writes to one table but the resolved view reads another; eventual-consistency lag; partial workspaces-domain implementation.
