Closes #13281
Problem
The issue reporter suggested changing
account.access_tokentouser.access_token, but that's a misdiagnosis.The real problem is a TypeScript type mismatch:
AccountextendsPartial<TokenEndpointResponse>, soaccess_tokenisstring | undefinedAccount.expires_atis declared asexpires_at?: number, also optionalJWTinterface declaresaccess_token: stringandexpires_at: numberas requiredThis causes a TypeScript compile error when following the documentation as written.
Fix
Added a type guard before assigning
account.access_tokenandaccount.expires_atto the token, consistent with the existingif (!token.refresh_token) throw new TypeError(...)pattern already used later in the same callback.Also removed the unused
type Userimport.Changes
type Userimportif (!account.access_token || !account.expires_at)type guard withTypeError
