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 tasks fails with the following error 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

This occurred due to the version error even Microsoft is aware of this and releasing the latest version by 

Next Update: Before Wednesday, October 17th, 2018 15:50 UTC.

As per the docs: https://blogs.msdn.microsoft.com/vsoservice/?p=17835.

Mention that 

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.

now, it is perfectly alright you can retry your deployment.
