How does error handling work when you use Invoke-Command over several computers?

Question

How does error handling work when I use Invoke-Command over many computers? For example, what if a computer name is misspelled or the user doesn't exist on a specific computer?

Invoke-Command -ComputerName Computer1,Computer2,Computer3  -ScriptBlock {        
    Get-LocalUser -Name User1 -ErrorAction SilentlyContinue 
}

From the docs: `Errors that result from the command that Invoke-Command runs are included in the command results.` — Paolo, Feb 24 '23 at 15:28
OP is asking about handling of `Invoke-Command` not `Get-LocalUser` @js2010 — Santiago Squarzon, Feb 24 '23 at 22:31

You can use the -ErrorVariable common parameter for this:

Invoke-Command -ComputerName Computer1, Computer2, doesNotexist -ScriptBlock {        
    Get-LocalUser -Name User1 -ErrorAction SilentlyContinue
} -ErrorAction SilentlyContinue -ErrorVariable errors

# error details here
$errors | Select-Object TargetObject, ErrorDetails
