[BUG] readFile error

readFile gives TypeError: Cannot read property 'F_OK' of undefined

I have

import { Workbook } from "exceljs";
let workbook = new Workbook();
files.forEach((file) => {
const data = workbook.csv.readFile(file.name)
})

Tried with workbook.xlsx.readFile and this gives same error.

I have version 3.8.1 installed.

Exceljs v4.1.0 : import { Workbook } from 'exceljs/excel' fix the problem with Electron.

Workaround if using this in electron

        fs.promises.readFile(path)
            .then(data => {
                workbook.xlsx.load(data.buffer)
                    .then()
                    .catch();
            }).catch();
