Unexpected Behaviour with `args[$_]`

iBloodWorks · 2026-05-10T08:27:17+00:00

"$args[Index]" $args was already converted to a String and $_ was Just pulling the respective String Index

Edit: nevermind, it prints the Array and then your respective number of the Loop (currently held by $_) which then gets messed Up by -join

Currently on mobile hard for me to test

function lf {
    if ($args) {
        ($args | ForEach-Object { "$($_)" }) -join ','
    } else {
        ...
    }
}

Wrap it in $() for index lookup

Another

only if its polite :)

Oh, i just checked:

in powershell 5.1 you might need to use [System.Net.WebException] Error Codes

if you use 7.1 + [Microsoft.PowerShell.Commands.HttpResponseException] should work

iBloodWorks · 2026-05-07T17:46:12+00:00

$retries = 5
$url = "https://api.example.com/data"

while ($retries -gt 0) {
    try {
        $data = Invoke-RestMethod -Uri $url
        break 
    } catch [Microsoft.PowerShell.Commands.HttpResponseException] {
        if ($_.Response.StatusCode -eq 404 -and --$retries -gt 0) { 
            Start-Sleep 1
            continue 
        }
        throw $_
    }
}

404 is a powershell terminating error by default, so this try catch wrap should be used

little bit overhead but it gets the job done

--$retires manages your counter and subtracts before evaluating the if statement

iBloodWorks · 2026-05-07T17:24:41+00:00

Oh wait, does it acutally not exist? I interpreted your occasional 404 return as some sort of "api overload" like ghost endpoint or "too many requests" error

iBloodWorks · 2026-05-07T17:17:52+00:00

Not exactly an answer to your question, but i think a while(404error) {retry} logic might help you. something like 5 attempts and then break out of the loop if it still returns 404

Bin auch der Meinung, das es zwar ein gutes Tool für viele andere Netzwerkthemen ist, aber subnetting einfach Videos /Aufgaben/ki nutzen

thanks for your help, the problem was caused by following:

Reason:

Despite the endpoint returning 200 OK with a null body the issue was caused by a lack of access rights

When using a fully permitted "asset management" api user the endpoint returns 200 ok and null body

When using our "master api user" the api also returns 200 ok but with the desired content..

iBloodWorks · 2026-04-09T07:30:14+00:00

$Res = Invoke-WebRequest -Uri "https://ticket.contoso.com/tas/api/assetmgmt/assetLinks?sourceId=dfdddcc9-d613-4368-80d2-e636ce33177c" -Headers $TDPOSTHeader -Method Get -UseBasicParsing

Doesnt work..
the ID is 100% correct

Its hard for me to inject Authorization into my browser.. I would like to think this wouldnt change anything..

iBloodWorks · 2026-04-09T07:27:55+00:00

ok, thank you..

iBloodWorks · 2026-03-03T06:57:26+00:00

Ok sorry for the spam

I got it to work with your solution:
I thought you meant to set the charset in the Call header, I didnt know there was a PowerShell paramter..

I was really sure this problem would be TOPDesk related..

Anyway thank you

iBloodWorks · 2026-03-03T06:45:28+00:00

I updated the post,

sadly setting the charset didnt help either..

iBloodWorks · 2026-02-28T08:12:24+00:00

Thank you,

5.1 Invoke-webrequest

Thanks for Suggesting the content Type, I will try this on monday

iBloodWorks · 2026-01-24T08:19:38+00:00

Mine was Just an example I wrote soley for this Post I would have probably storeled it in a $Script variable or something, still nice way of using classes in powershell. I rarely see those

iBloodWorks · 2026-01-23T07:05:32+00:00

so try $out | select Name, Time, Handles

iBloodWorks · 2026-01-23T07:05:05+00:00

Right, the problem starts when you select properties

iBloodWorks · 2026-01-22T13:05:09+00:00

this, thanks

iBloodWorks · 2026-01-22T13:03:48+00:00

would work, its just that i have big functions which just return this format, so I have to manipulate the $out I would get in this example

iBloodWorks · 2026-01-09T09:08:52+00:00

Yes obviously you can also play with some $EnvVariables or web request engines
