javascript imports errors

mIcHyAmRaNe

Hello,
i'm creating a small app using 'pyside2 + qml' to test and learn
it has 2 files

# main.py
from PySide2.QtWidgets import QApplication
from PySide2.QtQml import QQmlApplicationEngine

if __name__ == "__main__":
    app = QApplication([])
    engine = QQmlApplicationEngine()
    engine.load('./view.qml')
    app.exec_()

# view.qml
import QtQuick 2.15
import QtQuick.Controls 2.15
import QtQuick.Window 2.2
import "axios.min.js" as Axios

i'm trying to import some javascript libraries to test them inside my app but i got some errors:

when i import axios v0.21.1 : it works fine
but when i import axios new versions ( >0.21.1) it doesn't work and i get an error
TypeError: Value is null and could not be converted to an object

i tested different libraries like vanillajs and cheerio but getting errors too:

vanilla: ReferenceError: exports is not defined
cheerio: ReferenceError: exports is not defined

Any solution?
or in other words, how to use nodejs libraries with qml ?

Note: the JS files are taken from jsdelivr cdn

Thank you

It sounds like there were some backward-incompatible changes for versions >0.21.1

Where is the null value?

If I'm not mistaken, exports are NodeJS extensions, not part of ECMAScript (i.e. standard JavaScript). Qt's JavaScript engine supports ECMAScript 7 as of Qt 5.12.
