你好，我是go的新手，我正在尝试用go构建一个graphql服务，我使用go gqlgen包做到了这一点。现在，当安装和生成必要的文件时，我可以在docs选项卡上看到默认的TODO模式和解析器，当我实现或添加其他模式到模式文件时，我会从playground

中获得“Error fetching schema”
我的架构文件：

scalar Timestamp
type User {
  id: ID!
  email: String!
  password: String!
  otp_code: String!
  role: String!
  status: String!
  isEmailVerified: Boolean!
  otp_expire_time: Timestamp!
  createdAt: Timestamp!
  updatedAt: Timestamp!
  deletedAt: Timestamp!
}
input LoginCredential {
  email: String!
  password: String!
}
input UserSignUpDetail {
  email: String!
  password: String!
}
type AuthResponse {
  access_token: String!
  refresh_token: String!
}
type Mutation {
  UserLogin(input: LoginCredential!): AuthResponse!
  UserSignUp(input: UserSignUpDetail!): User!
}

架构解析程序文件：

package graph
// This file will be automatically regenerated based on the schema, any resolver implementations
// will be copied through when generating and any unknown code will be moved to the end.
import (
    "context"
    "fmt"
    "gatewayservice/graph/generated"
    "gatewayservice/graph/model"
)
// UserLogin is the resolver for the UserLogin field.
func (r *mutationResolver) UserLogin(ctx context.Context, input model.LoginCredential) (*model.AuthResponse, error) {
    panic(fmt.Errorf("not implemented: UserLogin - UserLogin"))
}
// UserSignUp is the resolver for the UserSignUp field.
func (r *mutationResolver) UserSignUp(ctx context.Context, input model.UserSignUpDetail) (*model.User, error) {
    panic(fmt.Errorf("not implemented: UserSignUp - UserSignUp"))
}
// Mutation returns generated.MutationResolver implementation.
func (r *Resolver) Mutation() generated.MutationResolver { return &mutationResolver{r} }
type mutationResolver struct{ *Resolver }

我需要帮助，谢谢。
