The assembly that contains the class must be provided to the assembly attribute for ACF Docker Image

We are currently in the process of migrating from windows to ACF 2021 docker images.

I have dropped the .dlls required for the dotnet integrations to work in the required directories and Coldfusion is able to find then when using cfobject but  I receieve the error "The assembly that contains the class must be provided to the assembly attribute"

My question is whether or not I need extra configuration for the local dlls or need to point to dlls on a remote server for the .net integration to work.

I have read

But it is still unclear to me.

Any insight is much apperciated.
