Node.JS Modules: TypeError: GraphQLJSClient is not a constructor

[SunboX]

Hi,

I'm importing the client like this:

import GraphQLJSClient from 'graphql-js-client'


const graphQLClient = new GraphQLJSClient(types, {
    fetcher: function fetcher(graphQLParams) {
        return fetch(url, {
            body: JSON.stringify(graphQLParams),
            method: 'POST',
            mode: 'cors',
            headers
        }).then((response) => response.json());
    }
})

inside a *.mjs file. But I'm getting the exception in the subject.

node index.mjs
TypeError: GraphQLJSClient is not a constructor
