I'm launching a `playwright` script on WebKit, Firefox, and Chromium on a VPS with Ubuntu 18.04. Using absolute paths on my VPS all three launch and operate properly if I type it into the terminal like this `cd /home/me/desktop/myCode && /usr/bin/npm run webkit > /home/me/desktop/errors.log 2>&1`. This makes me think that I have properly installed all of the dependencies from here: <https://github.com/microsoft/playwright/blob/master/docs/docker/Dockerfile.bionic>

However, when I use the exact same script but via cron, Firefox and Chromium launch and operate properly but the Webkit version starts (it does an async request before launching WebKit and this happens), but when WebKit tries to launch it fails the entire program. The cron script looks like this:

`8 14 * * * cd /home/me/desktop/myCode && /usr/bin/npm run webkit > /home/me/desktop/errors.log 2>&1` 

The error looks like this:

```

      throw er; // Unhandled 'error' event
      ^

Here's some code in Typescript, in case it's an issue with args passed into webkit:

```
export const getBrowser = async ({
  headless,
  browserName,
}: {
  headless: boolean;
  browserName: BrowserName;
}) => {
  switch (browserName) {
    case BrowserName.firefox:
      return await playwright.firefox.launch({
        headless: headless,
        args: ["--no-sandbox", "--disable-setuid-sandbox"],
      });
    case BrowserName.webkit:
      return await playwright.webkit.launch({
        headless: headless,
      });
    case BrowserName.chromium:
      return await playwright.chromium.launch({
        headless: headless,
        args: ["--no-sandbox", "--disable-setuid-sandbox"],
      });
  }
};

```
