Azure devops deployment failure : TypeError: Cannot read property 'scmUri' of undefined

Question

I have been facing this issue particularly today while deploying my application to the azure environment using Azure Devops.

One of the deployment task fails with the following eror message:

##[debug]Deployment Failed with Error: TypeError: Cannot read property 'scmUri' of undefined

When I retry to deploy a couple of times it succeeds and deployment is successfully done.

What is the issue causing this error?

Answer 1

Microsoft is aware:

We're investigating Intermittent failures of Release Pipelines in West Europe.

Customer using Azure App Service Deploy task in their Release Pipelines might see intermittent errors like: "##[error]TypeError: Cannot read property 'scmUri' of undefined"

Retrying the release may succeed.

Answer 2

The latest report from https://blogs.msdn.microsoft.com/vsoservice/?p=17835:

Final Update: Wednesday, October 17th 2018 20:14 UTC

We’ve confirmed that all systems are back to normal as of 2018/10/17 19:35 UTC. Our logs show the incident started on 2018/10/17 13:42 UTC and that during the 5 hours and 53 minutes that it took to resolve the issue. Customers using Azure App Service Deploy task in their Release Pipelines might see intermittent errors like: "##[error]TypeError: Cannot read property 'scmUri' of undefined". Sorry for any inconvenience this may have caused.

• Root Cause: Initial diagnosis from the Azure Web Apps team points to issues with a few of their back end nodes sending bad api responses.
• Chance of Re-occurrence: Medium
• Lessons Learned: We are working both minimizing resource-intensive activities in our post-deployment steps, and are also working targeting monitors specifically to detect post-deployment issues in the future.
• Incident Timeline: 5 hours & 23 minutes – 2018/10/17 13:42 UTC through 2018/10/17 19:35 UTC
