Enter a Cursor API key.

Error message

Enter a Cursor API key.

What it means

preparedConfig() requires an API key for the cursor_cloud and hermes_gateway adapter types: if apiKey is blank AND no organization secret binding (selectedBinding) is chosen, it throws. For cursor_cloud the message is specifically "Enter a Cursor API key." (for hermes_gateway it names the env key instead). The key may be entered directly or delegated to an org secret binding, but one of the two must be present.

Solutions

1. Paste a valid Cursor API key into the API key field.
2. Or select an existing organization secret binding via selectedBinding instead of a raw key.
3. If no org secret exists, create one for the Cursor key, then select it.
4. Re-check the field after switching adapter types — the key may have been cleared.

Example fix

// before: relying on an unset default
apiKey: "",
selectedBinding: null

// after: bind the org secret (or paste the key)
selectedBinding: { id: "org-secret-cursor", label: "CURSOR_API_KEY" }

const keyOk =
  !("cursor_cloud" === adapterType) ||
  apiKey.trim().length > 0 ||
  selectedBinding != null;
if (!keyOk) showError("Enter a Cursor API key.");

const hasCredential =
  (apiKey: string, binding: { id: string } | null): boolean =>
    apiKey.trim().length > 0 || binding != null;

try {
  const cfg = preparedConfig();
  submit(cfg);
} catch (e) {
  if (e instanceof Error && e.message.includes("API key")) {
    setKeyFieldError(e.message);
  } else throw e;
}

When it happens

Trigger: Submitting setup with adapterType "cursor_cloud", the API key field empty, and no org secret selected from selectedBinding.

Common situations: User expects the key to come from an environment/organization default but has not selected a binding; key was pasted with only whitespace; switching adapter types reset the field; first-time setup with no org secrets configured yet.
