Missing token

Error message

Missing token

What it means

In handleManualSubmit's paste-token mode (Trae/Windsurf providers configured in PASTE_TOKEN_PROVIDERS), the modal throws when the pasted token is empty after trimming. No /exchange call is made; this is pure client-side input validation before sending the token to /api/oauth/{provider}/exchange.

Solutions

1. Paste the API token into the input field and submit again
2. Check the clipboard actually contains the token (paste into a text editor first)
3. Trim stray whitespace/newlines from the pasted value

Example fix

// before
const token = pasteToken.trim();
if (!token) throw new Error("Missing token");
// after
const token = pasteToken.trim();
if (!token) throw new Error("Missing token — paste the token from your provider account page");

const token = pasteToken.trim();
if (!token) { setError("Paste a token first"); return; } // disable submit until non-empty

const hasToken = (s) => typeof s === 'string' && s.trim().length > 0;

null

When it happens

Trigger: User selects paste-token auth mode and clicks submit with an empty or whitespace-only token field.

Common situations: User forgot to paste the token; pasted only whitespace; clipboard paste silently failed; field was cleared by a re-render before submit.
