Hi Community,
I tried to finish the Kata #62 PerformaceAnalyzer.
I get an error inside the LCA:
Error trapped: Error thrown in implementation of OnPrepareFetch: Could not load file or assembly 'Skyline.DataMiner.Utils.PerformanceAnalyzer, Version=3.0.2.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
But I found the file in the correct location on the server as defined in the script: C:\Skyline DataMiner\ProtocolScripts\DllImport\skyline.dataminer.utils.performanceanalyzer\3.0.2\lib\net48\Skyline.DataMiner.Utils.PerformanceAnalyzer.dll
Why do I get this error message?
Hi Felix,
I encountered a similar issue to yours, and in my case, it was due to the GQI DxM not being enabled.
I had to do the step of configuring the Web.config described here GQI DxM | DataMiner Docs
After that, and after reloading everything, the LCA started showing everything correctly.


Which DataMiner version are you using? The Kata requires at least DataMiner 10.5.0 [CU1] or 10.5.4.

10.5.4.0-15588
Hi João,
I added the key as described, but the About page still shows "No DxM". Error persists.
