Problem with get-sensor -filter on empty return

JR-Otava commented 1 week ago

Describe the bug

$Objectparent | Get-Sensor -Filter $Local:filter -Recurse:$recurse

2024-09-12 03:48:57Z [Error ] : PRTGCFindSensor: Get-Sensor[] returned XML Exception(PRTG Bug), [

Steps to reproduce

Unfortunately hard to reproduce with a direct query

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

PSVersion      : 5.1.17763.6054
PSEdition      : Desktop
OS             : Microsoft Windows Server 2019 Datacenter
PrtgAPIVersion : 0.9.19
Culture        : en-US
CLRVersion     : .NET Framework 4.8 (528049)
PrtgVersion    : 24.3.98.1210
PrtgLanguage   : english.lng

Additional context

perhaps it does not like '_' ?

Or did our friends at Paessler change something in the search routine ?

After reproducing the crash can you please provide the output of $error[0].Exception.StackTrace. This will tell me where in the code the crash is happening

Hi.. Thanks for getting back to me.. This is all I get:

   at System.Collections.ArrayList.set_Item(Int32 index, Object value)
   at CallSite.Target(Closure , CallSite , Object , Object , Object )
   at PRTGCAddCachedSensors(Closure , FunctionContext )

But it might be operator error.. Let me get back to you...

This indicates the bug is in your code, somewhere in your PRTGCAddCachedSensors function, rather than in PrtgAPI. PrtgAPI does not have a function called PRTGCAddCachedSensors

Consider inspecting $error[0].ScriptStackTrace after reproducing the error to see exactly where in your script the issue is occurring
