Empty parenthesis on operations with no arguments

[lgberro]

What happened?

It's generating an empty argument operation. Not sure if this complies with GraphQL standard, but it breaks graphql-code-generator.

What did you expect?

Operation with no arguments shouldn't have empty parenthesis.

Minimal graphql.schema and models to reproduce

# schema 
type Mutation {
  deleteAccount: Boolean
}

# expected operation
mutation deleteAccount {
    deleteAccount
}

# generated operation
mutation deleteAccount() {
    deleteAccount
}

Hi.

I can't figure out how to reproduce the issue. I tried the following steps, but could not reproduce it. Please provide the exact steps for reproduction.

I defined the following in the schema.graphqls file of gqlgen.

type Mutation {
  deleteAccount: Boolean
}

I created a React.js project and used graphql-code-generator to execute graphql-codegen --config codegen.ts. This generated a gql.ts file, which looks like this.

/**
 * The graphql function is used to parse GraphQL queries into a document that can be used by GraphQL clients.
 */
export function graphql(source: "\n  mutation DeleteAccount {\n    deleteAccount\n  }\n"): (typeof documents)["\n  mutation DeleteAccount {\n    deleteAccount\n  }\n"];

It doesn't seem to have parentheses.

What is wrong with my reproduction steps? Could you please provide the correct library name, file names, etc.?
