Description

Hi everyone,

I'm facing again a panic using the CopyWithOptions() method. See above the example.

It seems this is related to map[x]interface{} @jinzhu

Having the same issue on map[string]interface{}. panic: reflect: call of reflect.Value.SetMapIndex on interface Value

@jinzhu any advice on this ? :)

rahulkhairwar commented 3 years ago

@jinzhu the below line doesn't actually set to's value to a map : to.Set(reflect.MakeMapWithSize(toType, from.Len())) Later, to.SetMapIndex(toKey, toValue) causes panic, as to is not of type map. Any way to resolve this?

This should been fixed in latest version
