Windows NRPE - invalid return code: -196608 Nagios Core

I have this Powershell script for monitoring AD sync status:

Param(
        [Parameter(Mandatory=$false,Position=0)] 
        [ValidateNotNullOrEmpty()]
        [int]$Warning=1,
        [Parameter(Mandatory=$false,Position=1)] 
        [ValidateNotNullOrEmpty()]
        [int]$Critical=5
)
# Variables
$SyncErrors=0
$NagiosStatus = 0
$NagiosOutput = ""
$Syncs = 0

# Get AD Replication Status for this DC
$SyncResults = Get-WmiObject -Namespace root\MicrosoftActiveDirectory -Class MSAD_ReplNeighbor -ComputerName $env:COMPUTERNAME |
    select SourceDsaCN, NamingContextDN, LastSyncResult, NumConsecutiveSyncFailures, @{N="LastSyncAttempt"; E={$_.ConvertToDateTime($_.TimeOfLastSyncAttempt)}}, @{N="LastSyncSuccess"; E={$_.ConvertToDateTime($_.TimeOfLastSyncSuccess)}} 

# Process result
foreach ($SyncResult in $SyncResults)
{
    if ($SyncResult.LastSyncResult -gt 0){
        $NagiosOutput += "$($SyncResult.NumConsecutiveSyncFailures) failed sync with DC $($SyncResult.SourceDsaCN) on $($SyncResult.NamingContextDN) at $($SyncResult.LastSyncAttempt), last success sync at $($SyncResult.LastSyncSuccess)."
        $SyncErrors++
        if ($SyncErrors -eq $Warning){
            $NagiosStatus = 1
        }
        elseif ($SyncErrors -eq $Critical) {
            $NagiosStatus = 2
        }           
    }
    else{
        $Syncs++
    }
}
# Nagios Output
$NagiosOutput += " | Syncs=$($Syncs);;;; SyncErrors=$($SyncErrors);$Warning;$Critical;;"
if ($NagiosStatus -eq 2) {
    Write-Host "CRITICAL: Replication error: $($NagiosOutput)"
    $host.SetShouldExit(2)

} 
elseif ($NagiosStatus -eq 1) {
    Write-Host "WARNING: Replication error: $($NagiosOutput)"
    $host.SetShouldExit(1)
    exit 1
} 
else{
    Write-Host "OK: replication is up and running.$($NagiosOutput)"
    $host.SetShouldExit(0)
    exit 0
}

nslient.ini:

[/settings/external scripts/scripts]

check_ad_replication = cmd /c echo \scripts\check_ad_replication.ps1; exit($lastexitcode) | powershell.exe - Command -

Script is located in script folder,

./check_nrpe -H 1.2.3.5

I (0.5.2.35 2018-01-28) seem to be doing fine...

From Nagios server getting

 ./check_nrpe -H 1.2.3.5 -c check_ad_replication -t 30

The command (check_ad_replication) returned an invalid return code: -196608

Tried to set exit 1 - 3 for exit codes but no changes, from Powershell command runs just fine. Does anyone knows what should be set for error codes

Issue solved, had to add quotes around exit codes, example:

$NagiosStatus -eq "2"
