No agent selected. Please select an agent before submitting

Error message

No agent selected. Please select an agent before submitting to the store.

What it means

ValueError raised inside create_store_submission when the agent graph lookup fails AND graph_id is empty or whitespace-only. It exists to give the marketplace submission UI an actionable message ('select an agent') instead of a cryptic not-found. Note the lookup itself is scoped to {id, version, userId}, so an empty string never matches and always lands here.

Solutions

1. Disable the submit button until a valid graph_id is selected in the UI.
2. Validate client-side: if (!graphId?.trim()) show 'select an agent' instead of calling the API.
3. In the API layer, declare graph_id as a required min-length-1 field so FastAPI returns 422 before the DB call.

Example fix

// before
<button onClick={() => submit({ graph_id: selectedAgent?.id ?? '' })}>Publish</button>
// after
<button disabled={!selectedAgent} onClick={() => submit({ graph_id: selectedAgent.id })}>Publish</button>

if (!form.graph_id || !form.graph_id.trim()) {
  setError('Select an agent to publish');
  return;
}
await api.createSubmission(form);

function hasSelectedAgent(graphId: string | null | undefined): graphId is string {
  return typeof graphId === 'string' && graphId.trim().length > 0;
}

When it happens

Trigger: POST /store/submissions with graph_id '' or ' ' — typically a frontend submitting the form before an agent is chosen, or a default-initialized empty agent field in state.

Common situations: Submit button enabled with no agent selected in the publish dialog; state reset to '' by a refetch but submission fired from stale closure; automated tests posting empty payloads.
