Not working with interface type?

I am using faker/v3 module. I understand that faker doesn't work with interface{}, however in the following code

package main

import (
	"fmt"
	"github.com/bxcodec/faker/v3"
)

type Request struct {
	Headers    map[string][]string
	Body       []byte
	StatusCode int
	Status     string
	Err        error
}

func main() {
	r := &Request{}
	err := faker.FakeData(r)
	fmt.Println(err)
}

I am getting interface{} not allowed error. I don't have any interface{} type element in the struct. The only interface is error, all others are collection type.

Ok, so error is of type interface. With Nil value faker can't tell which concrete implementation to use, hence the error. It is expected. I was dumb to realise is so late.

Maybe in wiki we should edit it from interface{} to interface with nil values to make it more clear to people?
