Error Get-Sensor - Die Eingabezeichenfolge hat das falsche Format.

[noaboa97]

Describe the bug

When running ``Get-Sensor` we get an error after the first page of 500 devices.

AUSFÜHRLICH: Get-Sensor: Synchronously executing request 
https://prtgserveruri/api/table.xml?content=sensors&columns=objid,name,probe,group,favorite,lastvalue,device,downtime,downtimetime,downtimesince,uptime,uptimetime,uptimesince,know

get-sensor : Die Eingabezeichenfolge hat das falsche Format.
In Zeile:1 Zeichen:12
+ $sensors = get-sensor
+            ~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-Sensor], FormatException
    + FullyQualifiedErrorId : System.FormatException,PrtgAPI.PowerShell.Cmdlets.GetSensor

I already tried with the parameter -count the error persists until I find a specific entry for us it's 643 where the get-sensor is able the retrieve 643 sensors. If the value is higher we get the above error.

It seems to be a PrtgAPI processing issue because I can download the table.xml in the browser fine and all items/sensors are in the xml file.

It would be very interesting to see, what causes this error since it is not showing up on the two other core servers.

• Server has been restarted already
• PRTG version is the same for all servers

Steps to reproduce

Unfortunatly this error only shows up on one of ours servers. We have 3 PRTG Core Servers and the error occurs only on the second one.

What is the output of 'Get-PrtgClient -Diagnostic'?
