Q_ARG missing, invokeMethod doesn't work currently with arguments in PySide2.

import sys

from PyQt5.QtCore import QObject, QMetaObject, QThread, pyqtSlot, Q_ARG
from PyQt5.QtWidgets import QApplication


class TestMeta(QObject):
    def __init__(self, parent=None):
        super().__init__(parent)

    @pyqtSlot(int)
    def method(self, name):
        print(f"Method is called with argument {name}")
        sys.exit(0)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    test_meta = TestMeta()
    thread = QThread()
    test_meta.moveToThread(thread)
    thread.start()
    QMetaObject.invokeMethod(test_meta, "method", Q_ARG('int', 12))
    sys.exit(app.exec_())

Method is called with argument 12
