System.ArgumentNullException: Value cannot be null. (Parameter 'key')

[mikeylee]

Describe the bug
I recently downloaded full-win-20.8.1.0, and running DEXTER against Saas AppD Controller, it detects I have 20.8.0.0 and prompts accordingly:
"Latest released version is 20.8.1.0, and yours is 20.8.0.0. Would you like to upgrade (y/n)?". So how do I get a copy of 20.8.1.0 ?

Also, when running Jobfile with Target.Type="APM" I get the following error:

System.ArgumentNullException: Value cannot be null. (Parameter 'key')
at System.Collections.Generic.Dictionary2.FindEntry(TKey key) at System.Collections.Generic.Dictionary2.TryGetValue(TKey key, TValue& value)
at AppDynamics.Dexter.ProcessingSteps.IndexAPMMetricsList.Execute(ProgramOptions programOptions, JobConfiguration jobConfiguration) in C:\Users\bhjel\RiderProjects\AppDynamics.DEXTER\ProcessingSteps\Index\IndexAPMMetricsList.cs:line 855

How do I address this error?

I have the same issue. I have tired multiple versions. I am getting the same error message and I am not able to run a report.
