Cannot represent non-enum value

Question

In my graphQL API(with typescript & type-graphql) I'm trying to run a mutation which inputType has an enum value defined as below

export enum GenderType {
  female = 'female',
  male = 'male',
}

registerEnumType(GenderType, {
  name: 'GenderType',
});

and I'm trying to execute this mutation.

mutation {
  registerStudent(data: {
    name: "John",
    gender: "male",
  }) {
    id
  }
}

but when I'm trying to execute the mutation it gives an error saying

"message": "Enum "GenderType" cannot represent non-enum value: "female". Did you mean the enum value "female" or "male"?",

I think this happens because how i defined the enum type using registerEnumType in type-graphql.

Found the problem...

Actually problem located at mutation object data that I passed.

First I pass gender type as a String that cause the problem.

mutation {
  registerStudent(data: {
    name: "John",
    gender: "male",
  }) {
    id
  }
}

This is wrong bcz It's a String, Program is expecting a value we defined in enums so pass enum values as it is.

mutation {
  registerStudent(data: {
    name: "John",
    gender: male,
  }) {
    id
  }
}
