I prefer to send the full logs ZIP file via email and not post it here.

Troubleshooting

I have already identified the issue and I have the fix. It is related to the version of the tunnel dependency. I will create a pull request shortly, but to the azure-devops-node-api repo, as that’s where the fix needs to go. I assume you will then change the version to your azure-devops-node-api dependency in the DownloadBuildArtifactsV0 task.

@omeshp can you please check if new tunnel version is resolving the issue. If yes, update task to take dependency on newer version of azure-devops-node-api.
