refresh_token is required
Error message
refresh_token is required
What it means
A non-empty refresh_token (or refreshToken) is mandatory: without it the stored Kiro credential can never be refreshed and would die at first expiry. The check fires when the field is absent, empty, or whitespace-only after trim.

Solutions
- Include the refresh_token (or refreshToken) field from the CLIProxyAPI auth document
- Re-authenticate via the external IdP flow to get a document containing the refresh token
- If the source redacts tokens, export with a non-redacting option or copy the token manually from the original store
- Never import an access-token-only blob — it will fail here by design
Example fix
// before
{ "access_token": "eyJ..." }
// after
{ "access_token": "eyJ...", "refresh_token": "0.AXoA..." } Defensive patterns
Strategy: validation
Validate before calling
const rt = auth.refresh_token ?? auth.refreshToken;
if (typeof rt !== 'string' || !rt.trim()) throw new Error('refresh_token missing from Kiro auth'); Type guard
function hasRefreshToken(a) {
return typeof a === 'object' && a !== null &&
['refresh_token', 'refreshToken'].some(k => typeof a[k] === 'string' && a[k].trim() !== '');
} Try / catch
try {
normalizeKiroExternalIdpAuth(auth);
} catch (e) {
if (e.message === 'refresh_token is required') {
console.error('Source redacted the refresh token; export without redaction or re-login');
}
throw e;
} Prevention
- Verify exports from other tools are not redacting refresh tokens before import
- Require refresh_token presence in your config schema validation
- Never build auth documents carrying only the access token
- Re-run the IdP login if the refresh token is unavailable — refresh tokens cannot be derived
When it happens
Trigger: Auth JSON missing refresh_token/refreshToken; refresh token blanked by a redaction/sanitization step before import; importing a document that only carries a short-lived access token.
Common situations: Exporting auth from a tool that redacts refresh tokens for security; copying only the access token into the JSON; an upstream login flow that stored the refresh token elsewhere.
Understand the failure class
Background: "Missing required field" and "field is required" errors: why libraries reject payloads that omit mandatory fields — this error's family across 20 libraries.
