I have the following config:

var config = new TypeAdapterConfig()
{
    // other configuration here
    RequireDestinationMemberSource = true,
};

// other mappings here

config.NewConfig<DataRow, Document>()
    .Map(d => d.Id, dr => dr.Field<int>("Id"))
    .IgnoreNonMapped(true);

When I now use config.Compile() to check the configurations I get an exception that on mapping DataRow to Document all properties (except Id of course) where neither configured to be mapped or ignored. My workaround for now is to use .RequireDestinationMemberSource(false) just for this one mapping, but shouldn't IgnoreNonMapped still work as inteded when using RequireDestinationMemberSource = true?
