.NET Framework assembly support added to Azure Logic Apps (Standard) XSLT transformations (GA)

Hi KentWeareMSFT ,
We are trying to implement a biztalk .Net codebase in the assembly, the code is carrying out a database lookup and some other things not yet identified by us.
When we tried to use that assembly in our map after following all the mentioned steps, we are getting undefined error in the transform XML action.
Is there any way we can get traces of the error in Logic App, to debug the error in our code or any way we can get the error details as the action is not providing any details on the error. 
Else do we have any precautionary measures to be taken in the code to be fixed in scenarios of migrating from biztalk to standard Logic App.
