Error in low code app, Cassandra not able to load file or assembly

Hi all,

Im currently working on an Automation Script compiled as a library that retrieves data from Cassandra and I want to display it in a low code app using the ad-hoc data query. Before I uploaded the library, I checked that my connection to Cassandra was working without a problem. Once I started moving things to low code apps, an error message showed up and it looks like from low code apps Cassandra is not being able to recognize or find ‘Microsoft.Extensions.Logging’.

Here is the full error message:

any thoughts on this matter?

Thank you.

Hi Carlos,

Looking at the exception, I could find the following entry:

… Could not load file or assembly Microsoft.Extensions.Logging

This leads me to believe that you are facing a known issue that we experience when your custom data source uses an external DLL. The custom data source will only be able to find DLLs that are located at C:\Skyline DataMiner\Files

As a workaround, could you try copying the DLL in C:\Skyline DataMiner\Files and validate the custom data source?

Hope it helps.

That issue is indeed known, to track the progess you can use following task: https://collaboration.dataminer.services/task/180830
