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

az vm list [--only-show-errors]
           [--resource-group]
           [--show-details]
           [--subscription]

Answer 2

Building on nftw's answer...

To make it faster/easier to find the error issue I used grep and less with a variable as follows:

$correlationId ='xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' # store your correlation ID here
Get-AzureRmLog -CorrelationId $correlationID -DetailedOutput | grep -C 10 $correlationID | less

In my testing the error was close to the top of the output. You could use less and the forward-slash key / and search "error" to find the error even quicker.
