Attempted to get IDP information when none exists.

Error message

Attempted to get IDP information when none exists.

What it means

Internal invariant of TokenCache (token_cache.ts:41): getIdpInfo() was called while idpInfo is undefined. The human workflow checks hasIdpInfo / passes idpInfo explicitly when calling getIdpInfo, so this should be unreachable from the public API. Reaching it indicates a driver bug or direct misuse of the @internal TokenCache.

Solutions

1. File a driver bug if reached via the public API with reproduction steps
2. With internal APIs, check cache.hasIdpInfo before cache.getIdpInfo()
3. Upgrade the driver to pick up any fixed regression

Example fix

// before
const idp = cache.getIdpInfo();

// after
const idp = cache.hasIdpInfo ? cache.getIdpInfo() : undefined;

function getIdpInfoSafe(cache: TokenCache): IdPInfo | undefined {
  return cache.hasIdpInfo ? cache.getIdpInfo() : undefined;
}

When it happens

Trigger: Calling the internal TokenCache.getIdpInfo() without first checking hasIdpInfo; or a regression where a workflow reads idpInfo before it was put into the cache via cache.put(response, idpInfo).

Common situations: Forked/monkeypatched auth providers bypassing the hasIdpInfo guard. A driver regression where getIdpInfo is reached before the two-step SASL IdPInfo response is cached.
