Throwing a regular error in a mutation

[sklymoshenko]

Hi, i am facing pretty much trivial bug. Basically when i am executing this mutations with already existed email, it returns a gql error "Cannot return null for non-nullable field User._id." so its still trying to return fields from user eventhoug i thrown an error.

mutation($password: String!, $email: String!, $name: String!) {
  register(password: $password, email: $email, name: $name) {
    _id
    name
  }
}

@Mutation(() => UserSchema, { nullable: true })
  async register(
    @Arg("name") name: string,
    @Arg("email") email: string,
    @Arg("password") password: string
  ): Promise<ISpUser | IError> {
    try {
      const SALT_ROUNDS = process.env.BCRYPT_SALT_ROUNDS as string;
      const SALT = await genSalt(+SALT_ROUNDS);
      const hashedPassword = await hash(password, SALT);

      const users: ISpUser[] = await UserModel.find({ email });

      if (users.length) throw new Error("Email is already in use");

      console.log("Here");

      const user = new UserModel({
        name,
        email,
        password: hashedPassword
      });

      await user.save();

      console.log("Here");

      return user;
    } catch (err) {
      console.log(err);
      return { message: err };
    }
  }

You can't return { message: err }; because you've declared GraphQL return type is UserSchema.

Yeah, its my fault bc of using a try{} catch{} and error goes there and i am trying to return something that isnt my declared return type.

Thanks.
