Using NodeJS promises for waiting the process of conversion completed - node.js

Question

I've been trying for 1 week without success to render the psd conversion through this nodejs module: https://www.npmjs.com/package/psd trying to make a confirmation message appear after converting all the images.
I don't know if the problem can be traced to my code or promise compliance, I've tried like 50 times to change every aspect of this code.
In psdconverter.js file
//! PSD COMPONENT MODULES
var PSD = require('psd');
//! file and extension MODULES
const fs = require('fs');
var path = require('path');
const PSDconverter = async (filename) => {
return new Promise((resolve, reject) => {
PSD.open('./img/' + filename).then(function (psd) {
let newfilename = filename.replace(/.psd/i, ""); //REPLACE CASE INSENSITIVE
psd.image.saveAsPng('./img/' + newfilename + '.png');
return newfilename;
}).then(function (res) {
console.log('PSD Conversion Finished!' + res);
resolve(res);
}).catch(function (err) {
console.log(err);
});
})
}
const EnumAndConvert = async () => {
return new Promise((resolve, reject) => {
//! READ DIR IMAGE AND CONVERTION PART
fs.readdir('./img/', (err, files) => {
if (err)
console.log(err + ' errore di conversione, non è stata trovata la cartella img!');
else {
for (let filename of files){
var ext = path.extname('./img/' + filename);
if (ext === '.PSD' || ext === '.psd')
await PSDconverter(filename);
}
}
})
resolve("Everything is converted successfully");
})
}
exports.PSDconverter = PSDconverter;
exports.EnumAndConvert = EnumAndConvert;
in index.js file
function PSDconverter() {
//! convertitore PSD
let EnumPSDAndConvert = require('./psdconverter.js');
EnumPSDAndConvert.EnumAndConvert().then((res) => { //dopo che è ritornata la Promise risolta continuo
console.log(res+"ciao");
})
}
ERROR RESULT:
await PSDconverter(filename);
^^^^^
SyntaxError: await is only valid in async function
When i want the first to be the last one.
Thank you for every help!

Ok the solution is:
index.js
function PSDconverter() {
//! convertitore PSD
let EnumPSDAndConvert = require('./psdconverter.js');
EnumPSDAndConvert.EnumAndConvert().then(() => {
console.log("Conversion Completed");
})
}
psdconverter.js
//! PSD COMPONENT MODULES
var PSD = require('psd');
//! file and extension MODULES
const fs = require('fs');
var path = require('path');
const PSDconverter = (filename) => { //without async
return PSD.open('./img/' + filename).then(function (psd) {
let newfilename = filename.replace(/.psd/i, ""); //REPLACE CASE INSENSITIVE
psd.image.saveAsPng('./img/' + newfilename + '.png');
return newfilename;
}).then(function (res) {
console.log('PSD Conversion Finished!' + res);
}).catch(function (err) {
console.log(err);
});
}
function readImgDir() {
return new Promise((resolve, reject) => {
fs.readdir('./img/', (err, files) => {
if (err)
console.log(err + ' errore di conversione, non è stata trovata la cartella img!');
else {
resolve(files);
}
})
})
}
const EnumAndConvert = async () => {
var files = await readImgDir(); //! READ DIR IMAGE AND CONVERTION PART
for (let filename of files) {
var ext = path.extname('./img/' + filename);
if (ext === '.PSD' || ext === '.psd')
await PSDconverter(filename);
}
}
exports.PSDconverter = PSDconverter;
exports.EnumAndConvert = EnumAndConvert;
If there are any suggestions on how to improve the code I would be curious.
Thanks Again
