Panic: invalid memory address or nil pointer dereference

[NateDogg-MM]

I created a gist for it gist but the take away is it crashes when both structs have pointers, so

type botRet struct {
	Id            *string  `json:"id"`
	Name      string   `json:"name"`
	
}

var ret struct {
	Bot *botRet `json:"bot"`
}

but if at least one doesn't have the pointer, it works

type botRet struct {
	Id            string `json:"id"`
	Name      string `json:"name"`
	
}

or

var ret struct {
	Bot botRet `json:"bot"`
}

Here's the output of the error

panic: runtime error: invalid memory address or nil pointer dereference

[NateDogg-MM]

@zxmantou sort of. i started using this package instead github.com/json-iterator/go
