Operand type clash: table is incompatible with nvarchar(max) | Procedure: tSQLt.AssertEqualsTable (0)

[tneve-azure]

I'm new to tSQLt and I am trying to test a simple stored procedure that moves data from one table to another. I have many table columns that are of datatype varchar(max) or nvarchar(max) and when I run my test case it calls a fSQLt.AssertEqualsTable stored procedure and it returns the below error.

I have tried changing the table column datatypes to varchar(255) or nvarchar(255) and I still get the same error below. I am not sure why I'm getting this error even when I change the column datatypes in the tables. Is there any tips or tricks that I can do to get my Assertion to work?
