Hi, may I please ask how you solved this error? On my side, I managed to trace it and found that the error occurs on the map function. This function is triggered by the ToModel. Not sure what exactly I am doing wrong. I am just a student playing a round with nop commerce.
What I did was to add a new supplier table. I am getting all these records from this table and would like to map it with a supplier model. I can see the data is received from the database and is passed to "ToModel" for mapping. But the actual mapping is not happening.
Did you create a map CreateMap<Supplier , Supplier Model>(); CreateMap<Supplier Model, Supplier >();
