Strapi V4 search by slug instead ID

:warning:
Wanna quickly point out that @paulkuhle solution isn’t working on Strapi v4.8.0
Paul’s solutions helped me a lot. This was the code I’m currently using:

in src/index.js

'use strict';

/** this is a test */

module.exports = {
  /**
   * An asynchronous register function that runs before
   * your application is initialized.
   *
   * This gives you an opportunity to extend code.
   */
  register({ strapi }) {
    const extensionService = strapi.plugin("graphql").service("extension");

    const extension = () => ({
      typeDefs: `
        type Query {
          faqQuestion(slug: String!): FaqQuestionEntityResponse
        }
      `,
      resolvers: {
        Query: {
          faqQuestion: {
            resolve: async (parent, args, context) => {
              const { toEntityResponse } = strapi.service(
                "plugin::graphql.format"
              ).returnTypes;
              const data = await strapi.services["api::faq-question.faq-question"].find({
                filters: { slug: args.slug },
              });
              const response = toEntityResponse(data.results[0]);
              return response;
            },
          },
        },
      },
    });

    extensionService.use(extension);
  },

  /**
   * An asynchronous bootstrap function that runs before
   * your application gets started.
   *
   * This gives you an opportunity to set up your data model,
   * run jobs, or perform some special logic.
   */
  bootstrap(/*{ strapi }*/) {},
};

In Strapi’s latest patch v2.8.0 the code isn’t working anymore because ID is now required when querying for singular content type requests:

Field \"faqQuestion\" argument \"id\" of type \"ID!\" is required, but it was not provided.

don’t know why they did it, but I’m looking for a solution because this breaks my whole app… :frowning:
