The method or operation is not implemented: AutoMapperConfiguration.Mapper.Map<TSource, TDestination>(source)

Hi all, I do not know if I'm in the right forum. I know that this subject has already been treated unfortunately, but for my case I am lost. In fact I am new in the development on nopcommerce. I created my plugin nop 3.90 following the documentation of the nopcommerce site and everything seems to work, my plugin was well displayed Admin. When I click on the configure button of the plugin here is the error that appears:

Server Error in '/' Application.
The method or operation is not implemented.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.NotImplementedException: The method or operation is not implemented.

Source Error: 


Line 60:         public static TDestination MapTo<TSource, TDestination>(this TSource source)
Line 61:         {
Line 62:             return AutoMapperConfiguration.Mapper.Map<TSource, TDestination>(source);
Line 63:         }
Line 64: 

I saw a similar example on the forum unfortunately that does not solve my problem. Thank you for your help
