name = graphene.String(required=True)
phone = graphene.Int(required=True)
guest = graphene.Field(GuestType)
#classmethod
def mutate(cls, root,info,name,phone):
guest = Guest(name=name, phone=phone)
guest.save()
return GuestMutation(name=name, phone=phone)
class Mutation(graphene.ObjectType):

Answer 1

You're returning the wrong information:
class GuestMutation (graphene.Mutation):
# What you accept as input
class Arguments:
name = graphene.String(required=True)
phone = graphene.Int(required=True)
# What you return as output
guest = graphene.Field(GuestType)
So as mentioned, you need to return the guest you created.
