Azure Automation truncates job error stream summary

Question

Azure Automation truncates job error stream summary

Filipe Simões 20

I have written a script to monitor Azure Automation jobs.

It goes through the jobs and gets its error's stream and uses it add to an object among other properties. The issue is that, when executing from an Azure Automation account, the job's "summary" property, it gets truncated to about 85 chars. When executing from my laptop, all works as expected and I get the full property value.
Example from my computer:

,"Cannot validate argument on parameter 'Identity'. The argument is null. Provide a valid value for the argument, and then try running the command again.",

Same string from the error log when the script is ran from Azure Automation Runbook:

,"Cannot validate argument on parameter 'Identity'. The argument is null. Provide ...",

The code I have executing is:

$JobErrorOutputStreamEvents = Get-AzAutomationJobOutput -Id $Job.JobId -ResourceGroupName $ResourceGroupName -AutomationAccountName $AutomationAccountName -Stream Error

# Logs job error events
        foreach ($JobErrorOutputStreamEvent in $JobErrorOutputStreamEvents) {
            # Adds the Error streams to Job Errors Log
            $Properties = [ordered] @{
                Runbook = $Runbook.Name
                JobId = $Job.JobId
                JobStatus = $Job.Status
                JobStatusDetails = $Job.StatusDetails
                EventTime = $JobErrorOutputStreamEvent.Time
                Summary = $JobErrorOutputStreamEvent.Summary
                JobStartTime = $Job.StartTime
                JobEndTime = $Job.EndTime
                AutomationAccountName = $AutomationAccountName
                ResourceGroupName = $ResourceGroupName
                Subscription = $SubcriptionName
            }
            $JobErrorsLog += New-Object -TypeName PSObject -Property $Properties
    
            $Time = Get-Date -Format "yyyy-MM-dd hh:mm:ss K"
            $MsgErrorFoundInJob = "[Info] Runbook `"$($Runbook.Name)`" - Error found in Job ID `"$($Job.JobId)`", happening at $($JobErrorOutputStreamEvent.Time)!"
            Write-Output $MsgErrorFoundInJob
            $Log += "[$Time] $($MsgErrorFoundInJob)"
        }

Once more, I must stress that the code is fine and I get the full error "Summary" if executing from my computer.
Tried using Select-Object -ExpandProperty Summary, but it does not change anything.

Can someone help?

hello you can use Get-AzAutomationJobOutputRecord to get the complete error output

$JobErrorOutputStreamEvents = Get-AzAutomationJobOutput -Id $Job.JobId -ResourceGroupName $ResourceGroupName -AutomationAccountName $AutomationAccountName -Stream Error
$FullErrorRecords = $JobErrorOutputStreamEvents | Get-AzAutomationJobOutputRecord

foreach ($FullErrorRecord in $FullErrorRecords) {
    $Summary = $FullErrorRecord.Value  # Access full error message here
    ...
}

Try changing the Summary = $JobErrorOutputStreamEvent.Summary to Summary = $JobErrorOutputStreamEvent.Summary | To-String -Width 250.

Those ellipsis at the end of the value look like the default formatting of the object is the problem.

I know nothing about the environment that the automation uses to run the script, but if it's the default formatting that's causing the problem you can try this (I don't know if there is a "host" in that environment!):

$pshost = get-host $pswindow = $pshost.ui.rawui $newsize = $pswindow.buffersize $newsize.height = 3000 $newsize.width = 150 $pswindow.buffersize = $newsize

You can also try Summary = $JobErrorOutputStreamEvent | Select-Object -Expand Summary

The problem is that I have no knowledge of what object types are in the $JobErrorOutputStreamEvent variable or the host in which the script runs. I'm only guessing at the problem here.

Filipe Simões, thank you for reporting this issue with details.

I tested the shared cmdlet for Get-AzAutomationJobOutput and noticed that the truncation of output is only happening for runbook of type PowerShell v5.1

You can use the same code in a new runbook of PowerShell v7.2 type and this should not be an issue.

I will try to get some more details about this for PowerShell v5.1 type runbook and share here.

Hope this helps.
