Hey there.
Can you widen the logs you’ve shared a bit to show at what point exactly in the analysis the failure occurs?
Based on some other reports, it’s possible the token being used to make the connection between SonarCloud and Azure DevOps is (no longer) valid.
Take a look at your project-level Administration > Pull Requests or organization-level Administration > Organization settings > Azure DevOps connectivity management and make sure a valid token is set.
