Building on @nftw:

$deploymentGroupName = 'deploymentGroupName'
$correlationId = ((Get-AzureRMLog -ResourceGroup $deploymentGroupName)[0]).CorrelationId
$logentry = (Get-AzureRMLog -CorrelationId $correlationId -DetailedOutput)
#$logentry
$rawStatusMessage = $logentry.Properties
$status = $rawStatusMessage.Content.statusMessage | ConvertFrom-Json
$status.error.details
$status.error.details.details
