Shouldn’t the code below change the default route /api/emissions ?

Nothing happens?
Can a good human being help me?

// /api/emission/controllers/emission.js
const { createCoreController } = require('@strapi/strapi').factories;
module.exports = createCoreController('api::emission.emission'), ({ strapi }) =>  ({
  async find(ctx) {
    // some custom logic here
    return { data: 'some data' };
  },
});

I think , this is not allowed in strapi . you need to return object which should contain results key in return statement

return { results: { dataKey: 'dataValue' }, pagination: {} }

at api side it will give below response (data field value is results field value in return and meta field value is 2nd object pagination)
{ "data": { "dataKey": "dataValue" }, "meta": { "pagination": {} } }

pagination field in response is optional if you can not give that is fine but results key is mandatory otherwise it will give error .
eg return { results: { dataKey: 'dataValue' } }

it will api response as below
{ "data": { "dataKey": "dataValue" }, "meta": {} }
