Error while running Theia playwright electron

[Hanksha]

Hi,

I'm trying to write a playwright test for a Theia based electron app. The first test itself works alright but there's a problem in the background and it throws errors like these:

 Error: TypeError: Cannot read properties of undefined (reading 'require')

The errors are not always the same, sometimes it's an error related to the plugin API.

Did anyone else encounter something similar and knows how to resolve it?

I run the tests via playwright test --config=./configs/playwright.config.ts and the config is:

import { PlaywrightTestConfig } from "@playwright/test";

const config: PlaywrightTestConfig = {
    testDir: "../lib/tests",
    testMatch: ["**/*.test.js"],
    workers: 1,
    timeout: 120 * 1000,
    use: {
        // trace: "on",
        baseURL: "http://localhost:3000",
        browserName: "chromium",
        screenshot: "only-on-failure",
        viewport: { width: 1920, height: 1080 },
        permissions: ["clipboard-read", "clipboard-write"]
    },
    snapshotDir: "../tests/snapshots",
    expect: {
        toMatchSnapshot: { threshold: 0.15 }
    },
    preserveOutput: "failures-only",
    reporter: [["list"], ["junit", { outputFile: "./junit-results/results.xml" }], ["allure-playwright"]]
};

export default config;

The app loading:

const electronAppPath = path.join(__dirname, "..", "..", "..", "..", "electron-app");
app = await TheiaAppLoader.load(
    {
        browser,
        playwright,
        useElectron: {
            electronAppPath
        }
    },
    new TheiaWorkspace(workspaceDir)
);

This is now working after upgrading to Theia 1.60.0.
