jwt-go/parser.go

Line 131 in dc14462 err = dec.Decode(&claims)

Since this function takes claims as Claims, if you pass anything other than MapClaims{}, you'll get an unmarshalling error: Error verifying token: json: cannot unmarshal object into Go value of type jwt.Claims

ah, if you use &MapClaims{} instead of MapClaims{} it will work. See https://stackoverflow.com/questions/50564341/pointer-to-an-interface-vs-interface-holding-a-pointer-when-unmarshaling-json for more explanations
