Get-SystemInformation: Deserializing the object of type PrtgAPI.SysInfoData1[[PrtgAPI.DeviceProcessInfo

[Ash258]

Describe the bug

For one of my ubuntu host PRTG cannot get proper system information. Instead of datetime it returns Unavailable

Steps to reproduce

There is no direct steps to reproduce, unless you know how to simulate the process to get unavailable data.
To reproduce it should be possible to use the json data at the bottom on some test device or just mock them.

pwsh@7.2.0-preview.9> Get-SystemInfo -Id 2167
Get-SystemInfo: There was an error deserializing the object of type PrtgAPI.SysInfoData`1[[PrtgAPI.DeviceProcessInfo, PrtgAPI, Version=0.9.0.0, Culture=neutral, PublicKeyToken=null]]. String 'Unavailable' was not recognized as a valid DateTime.

What is the output of Get-PrtgClient -Diagnostic?

pwsh@7.2.0-preview.9> Get-PrtgClient -Diagnostic

Hi @Ash258,

Please be advised I have pushed a new pre-release version of PrtgAPI which should have a fix for this issue. Please see the manual installation instructions for information on running this version
