feathersjs sequelize call stored procedure by hook doesn't resolve - stored-procedures

Question

I have a problem creating a hook calling a stored procedure.
My custom service hooks (customservice.hooks.js) are :
const callstored = require('../../hooks/callstored')
module.exports = {
before: {
all: [],
find: [callstored()],
get: [],
create: [],
update: [],
patch: [],
remove: []
},
...
My service class (customservice.class.js):
const mysql = require('mysql')
class Service {
constructor (options) {
this.options = options || {};
}
find (params) {
return Promise.resolve( [] );
}
get (id, params) {
return Promise.resolve({
id, text: `A new message with ID: ${id}!`
});
}
create (data, params) {
if (Array.isArray(data)) {
return Promise.all(data.map(current => this.create(current)));
}
return Promise.resolve(data);
}
update (id, data, params) {
return Promise.resolve(data);
}
patch (id, data, params) {
return Promise.resolve(data);
}
remove (id, params) {
return Promise.resolve({ id });
}
}
module.exports = function (options) {
return new Service(options);
};
module.exports.Service = Service;
And my service (customservice.service.js) :
const createService = require('./rankingvotes.class.js');
const hooks = require('./rankingvotes.hooks');
module.exports = function (app) {
const paginate = app.get('paginate');
const options = {
name: 'rankingvotes',
paginate
};
// Initialize our service with any options it requires
app.use('/rankingvotes', createService(options));
// Get our initialized service so that we can register hooks and filters
const service = app.service('rankingvotes');
service.hooks(hooks);
app.publish(() => {
});
};
And finally my hook is (callstored.js)
const Sequelize = require('sequelize');
module.exports = function () {
return function (hook) {
sequelize = hook.app.get('sequelizeClient');
let result=[];
return sequelize.query('CALL RANKING();',{
nest: true,
raw: true }).then(function(response){
console.log(response[0]) //data are correct
hook.data=response[0];
return hook;
}).error(function(err){
console.log(err);
return hook;
});
}
}
If I check the console I got data correctly, but nothing calling from a REST client like Postman.
Any idea? Thank you.

If you want to change the response you have to set hook.result.
const Sequelize = require('sequelize');
module.exports = function () {
return async hook => {
try {
const sequelize = hook.app.get('sequelizeClient');
const response = await sequelize.query('CALL RANKING();',{
nest: true,
raw: true
});
console.log(response[0]) //data are correct
context.result = response[0];
} catch(error) {
console.error(error);
}
return hook;
}
}
hook.data is the request data and is only available for create, update and patch.
Keep in mind that setting hook.result will skip your custom service find if it is set in a before hook.
