Feathersjs validation method using ldapjs module problem - node.js

Question

I want to write a function that adds the params of an ldap server after checking if the binding with server is right otherwise the data won't get added in the db ; i have to use feathers js. I tried to write a couple of lines to validate the params before adding them to the db :
const ldap=require("ldapjs"); but the problem is that when i do console.log(errors) inside and outside of ldap.bind function : i noticed that the result is only visible inside the function but not to the rest of the code ! I need it to be visible to the other parts as well so that I can use it , I want to know how to fix that.
this is the code and what the console.log has as a result.
module.exports = (ldapConnexion, mode = "create") => {
const errors = {
url_path: [],
browsingAccount: [],
password: [],
userSearchBase:[],
};
const client=ldap.createClient({url:ldapConnexion.url_path})
client.bind(ldapConnexion.browsingAccount,ldapConnexion.password,function(err){
if (err){errors.browsingAccount.push("unvalid credentials:"+err);console.log(err)}})
console.log(errors)
const hasErrors = Object.keys(errors).reduce(
(res, errorType) =>
res || (errors[errorType] && errors[errorType].length > 0),
false
);
return { errors, hasErrors };
}

to do that we can implement the code this way : if this can interrest someone
in a different file do :
const ldap = require('ldapjs');
module.exports = (ldapConnexion, mode = "create",cb) => {
const errors = {
url_path: [],
browsingAccount: [],
password: [],
userSearchBase: [],
};
var opts ={
rejectUnauthorized: false, // To force the client not to check self-signed certificates
}
//create the ldap client with the list of informations mentionned in the form
var client = ldap.createClient({
url:ldapConnexion.url_path, tlsOptions:opts
});
client.bind(ldapConnexion.browsingAccount, ldapConnexion.password, function (err) {
if (err) {
errors.browsingAccount.push("unvalid credentials:" + err.message);
//console.log(errors);
cb(errors,true);
client.unbind(function(err){if(err){console.log(err)}});
} client.unbind(function(err){if(err){console.log(err)}});
})
// console.log(errors)
if (!ldapConnexion.url_path) {
errors.url_path.push("Url obligatoire");
}
if (!ldapConnexion.browsingAccount) {
errors.browsingAccount.push("le compte lecteur est obligatoire");
}
if (!ldapConnexion.password) {
errors.password.push("le mot de passe est obligatoire");
}
const hasErrors = Object.keys(errors).reduce(
(res, errorType) =>
res || (errors[errorType] && errors[errorType].length > 0),
false
);
cb(errors, hasErrors)
}
in the hooks :
const validateConnexionHook = function (mode = "create") {
return context => {
return new Promise((resolve, reject) => {
const ldapConnexion = context.data || {};
validateConnexion(ldapConnexion, mode, (errors, hasErrors) => {
console.log('**************')
// console.log(errors);
console.log(hasErrors);
if (hasErrors) {
context.error = errors;
reject(errors)
}
else setTimeout(function () { resolve(); }, 3000);
})
})
}
}
