Failed to resolve skill after publish

Error message

Failed to resolve skill after publish

What it means

After a successful publish (store.update plus pointing activeVersionId at the new version), the handler re-reads the skill via getByIdResolved to return the fully resolved record. If that read returns null, internal state is inconsistent, so it throws a 500. This is a server-side consistency failure, not a client input problem.

Solutions

Retry the publish request; transient replication/timing issues may self-heal
Verify the stored skill still exists (GET the skill by id) — if it was deleted concurrently, recreate it
Check your storage adapter implementation and version tables for consistency (activeVersionId points at an existing version row)
Report/pin the issue if using a custom storage adapter; test with the default adapter to isolate

Defensive patterns

Strategy: retry

Validate before calling

// Pre-check that the skill exists and can be read back before publishing
const before = await fetch(`${baseUrl}/api/stored/skills/${id}`).then(r => r.json());
if (!before?.id) throw new Error('Skill not found; publish would be a no-op');

Try / catch

try {
  return await publishSkill({ id, skillPath });
} catch (e) {
  if (String(e?.message).includes('Failed to resolve skill after publish')) {
    // transient consistency issue — retry with backoff
    await new Promise(r => setTimeout(r, 250));
    return publishSkill({ id, skillPath });
  }
  throw e;
}

Prevention

Avoid deleting the skill concurrently with publishing
Keep storage adapter and @mastra/core versions aligned
Prefer maintained adapters (LibSQL/PG) over custom joins for resolved reads
Add an alert/log when publish responses return 500 so consistency bugs surface early

When it happens

Trigger: POST to the publish route when getByIdResolved(storedSkillId) returns null immediately after update() succeeded — e.g. the storage adapter fails to join the thin record with its active version, or the row was deleted concurrently.

Common situations: Custom or buggy storage adapters whose resolved-read join silently returns null; concurrent deletion of the skill between update and re-read; database replication lag in read-replica setups; schema migrations leaving versions orphaned.
