API/Scripting/ExecuteCommand - working but no result

Describe the bug
I get no result object from "API/Scripting/ExecuteCommand". It seems to timeout after 30 seconds and I get a 404 exception.

To Reproduce

$server = "http://xxx.xxx.xx:5000"
$headers = @{ Authorization = "Basic $([System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes("xxx:xxx")))" }

$g = Invoke-WebRequest -Uri "$server/api/Devices" -Method Get -Headers $headers -ContentType "application/json" -UseBasicParsing -ErrorAction Stop
($g.Content | ConvertFrom-Json) | Select-Object organizationID, id, deviceName, osDescription | Out-GridView -OutputMode Multiple | % {
    $d = $_
    $p = Invoke-WebRequest -Uri "$server/API/Scripting/ExecuteCommand/PSCore/$($d.id)" -Method Post -Headers $headers -Body "Get-Culture"  -ContentType "application/json" -UseBasicParsing -ErrorAction Stop
}

$g = Invoke-WebRequest -Uri "$server/API/ScriptResults" -Method Get -Headers $headers -ContentType "text/plain" -UseBasicParsing -OutFile "$env:TEMP\r.json"  -UseBasicParsing -ErrorAction Stop
(Get-Content  "$env:TEMP\r.json" | ConvertFrom-Json) | Out-GridView -OutputMode Multiple

Expected Behavior
Get a result similar to the one from API/ScriptResults

Start by tracing the API/Scripting/ExecuteCommand/PSCore/{device id} endpoint and compare its behavior with API/ScriptResults. Reproduce the PowerShell request using the supplied example; done means ExecuteCommand returns a result without the 30-second timeout or 404 exception.
