UiPath-ADAv1 Orchestrator and Integration Service Practice Question
An automation developer has configured an Integration Service connection to a Google Drive account using OAuth 2.0. The connection was working, but suddenly all activities using it fail with an authentication error. Upon checking, the developer finds that the refresh token has been revoked. What is the most likely cause?
⚠ Common exam trap
The trap here is assuming that OAuth 2.0 client secrets expire frequently or that service account changes affect Integration Service connections, when in fact user-initiated revocation is a common cause of refresh token invalidation.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user who authorized the connection revoked access from their Google account settings.
The failure is due to a revoked refresh token, which commonly happens when the user who granted access removes the application from their account permissions. This invalidates the token and prevents the connection from refreshing access. Other options like client secret expiration or license issues would not cause a specific refresh token revocation, and they would typically affect multiple connections or produce different errors.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The OAuth 2.0 client secret expired after 90 days.
Why it's wrong here
Client secrets in OAuth 2.0 are long-lived credentials that do not automatically expire after 90 days. They remain valid until manually rotated or revoked by the administrator. The scenario describes a revoked refresh token, not an expired secret. If the client secret had expired, all connections using that client would fail simultaneously, but the issue is specific to one connection's refresh token being revoked.
- ✗
The UiPath Robot service account password was changed, invalidating the connection.
Why it's wrong here
Integration Service connections are independent of the Robot service account credentials. The Robot service account is used for running jobs on machines, not for authenticating to external services like Google Drive. Changing the service account password would not affect OAuth 2.0 refresh tokens stored in Integration Service. The error is specific to the external service authentication.
- ✓
The user who authorized the connection revoked access from their Google account settings.
Why this is correct
When a user revokes access for an application in their Google account security settings, the refresh token associated with that connection becomes invalid. This causes authentication failures for any subsequent token refresh attempts. The connection will no longer be able to obtain new access tokens, resulting in the observed errors. Reauthorizing the connection is required to restore functionality.
- ✗
The Integration Service license expired, disabling all connections.
Why it's wrong here
An expired Integration Service license would typically affect all connections and prevent new ones from being created, but it would not specifically revoke a refresh token. The error indicates that the refresh token itself is invalid, which points to a revocation event on the provider side. License expiration would produce different error messages related to licensing, not authentication.
