Custodian Not Found

404 · NotFoundError · Custodian not found · App not found · Custodian squad not found.

Usual causes:

  • A hard-coded or stale agent / app / squad ID.
  • The key belongs to a different account than the one that created the agent.
  • .deploy() never ran before .chat().
  • The agent was created against a different base_url.

Fix: use the object .deploy() returns instead of typing IDs.

app = Custodian(model="gpt-4o", system_prompt="You are helpful.").deploy()
app.chat("Hello") # app carries its own ID
const app = await new Custodian({ model: "gpt-4o", systemPrompt: "You are helpful." }).deploy();
await app.chat("Hello");
