Hello DataMiner Dojo community,
Recently, I discovered from one of the severs that when opening the Client test tool, I encountered the error as shown below:
(error reads: System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.)
The DMA setup is with the failover pair.
DMA version: 10.3 CU2
Is there any files or configuration I should check to resolve the issue?
Thank you for the help.
Could you copy-paste the full stacktrace of the exception? This may indicate the exact assembly that could not be loaded.
Are the following 2 files present in the C:\Skyline DataMiner\Files\ folder?
SLAnalyticsTypes.dll
SLCcaEndPointTypes.dll

I was able to simulate this by removing Newtonsoft.Json.dll from the folder. Can you check that file is present and has Fileversion 13.0.2.27524 ?

The file is present and version is 11.0.2.21924
DataMiner 10.3.0 CU2 ships with version 13.0.2.27524 so I would expect more problems running the software. Can you check in the progess.log of the upgrade to 10.3.0 CU2 (if still available) if there were any errors replacing this file?

Hello Bert,
in the progress.log, I saw the following which could be the root cause of the issue:

Hello Bert,
For the exception, I have updated in my post.
The following 2 files – SLAnalyticsTypes.dll and SLCcaEndPointTypes.dll are present in the C:Skyline DataMinerFiles as well.
