Accessibility test case using axe core and webdriverjs - Error: UnhandledPromiseRejectionWarning

Question

I have an automated WebUI tesing case which is supposed to test a website on accessibility. It's working fine and giving me the required output locally on my Mac but unfortunately failing on my VM (Ubuntu 22.04.1 LTS).

This is the source code:

    const AxeBuilder = require('@axe-core/webdriverjs');
    const { Builder, By, Key, promise, until } = require('selenium-webdriver');
    const firefox = require('selenium-webdriver/firefox');
    promise.USE_PROMISE_MANAGER = false;
    const options = new firefox.Options();
    options.headless();
    const driver = new Builder()
        .forBrowser('firefox')
        .setFirefoxOptions(options)
        .build();
    
    async function main() {
        await driver.get('https://digital.hamburg.de/').then(() => {
        new AxeBuilder(driver).analyze(async (err, results) => {
            try {
                console.log(results.violations);
            } catch (e) {
                console.log("Something went wrong", e.message);
            } finally {
                await driver.close()
            }
    
        });
    
    });
    }
    
    main();

And the following my output which I'm getting from the VM:

I'm quite a newbie at this and glad for any help.
