How can I troubleshoot Azure ARM template validation errors?

Question

I have made some small changes to an Azure ARM template file and now when I try to deploy or validate via the xplat cli I get this message.

error: Inval

Answer 1

I was running in the same issue. Basically, I couldn't get any details passed "InvalidTemplateDeployment".

I added my ARM template in a Visual Studio: Azure Resource Group project template and tried to deploy it. I got verbose details in the Output tab. That helped me solve my problem.

In my case it was the name of the cluster, it can only be small letters and numbers.
