Add device objects to the Azure group in Powershell foreach - azure

Question

I am trying to run a simple Powershell command let, which is listing all devices matching name criteria and in the next step is moving these devices to a select Azure group.
I tried with:
$result = Get-AzureADDevice -All $True -SearchString "LAP-BK" | ForEach-Object -Process {Add-AzureADGroupMember -ObjectId "25f94620-d850-4ec6-9476-050429d44926" -RefObjectId "$result.ObjectId"}
but that throwing errors. I also tried with
$result = Get-AzureADDevice -All $True -SearchString "LAP-BK" |Select-Object ObjectId
forEach ($item in $result)
{
Add-AzureADGroupMember -ObjectId "25f94620-d850-4ec6-9476-050429d44926" -RefObjectId "$item"
}
exit
The error are various, the last one I get was:
Error occurred while executing AddGroupMember Code: Request_BadRequest Message: Invalid object identifier ' #{ObjectId=debb95af-9h1f-49d6-ad84-8438f9c99b10}'. RequestId: 6df36830-7708-4f6b-b836-cd065f5f60b1

I tried to figure out the error from my end by running your script line by line, and I was able to find exactly where it was occurring:
Referring to Jamesyumnam article, I was able to successfully create and run the below script.
$groupName = "<groupName>"
Connect-AzureAD
$groupObject = Get-AzureADGroup -SearchString $groupName
$outcome = Get-AzureADDevice -SearchString "xxxxxx" | select-object objectID
try{
foreach ($item in $outcome)
{
$deviceObj = Get-AzureADDevice -SearchString $item.DeviceName
Add-AzureADGroupMember -ObjectId $groupObject.ObjectId -RefObjectId $item.ObjectId
}
}
catch {
Write-Host "Device not existed"
}
Executed in Azure PowerShell:

Note: It will be more helpful if you include try{} catch{} blocks in your code to find these kinds of blockers.
