await browser.getPuppeteer() is not working in Firefox tests running

[VladSelikh]

Hey guys!
I receive the error while running the command await browser.getPuppeteer() in my tests. I need a Puppeteer browser to access the clipboard value. The Error text is:
TypeError [ERR_INVALID_URL]: Invalid URL
I've set 'moz:debuggerAddress' as true in my caps.
Could you please advise whether I can run this command and use Puppeteer browser for Firefox at all?
If yes, what am I doing wrong?
If no, is there any other way to access clipboard in Firefox?

I've set 'moz:debuggerAddress' as true in my caps.

Why do you set the capability like that?

[VladSelikh]

Without this one set in true I still have the same Error, just thought that in this way I would foresee the suggestions to do that😁

Are you running your automation script locally?

[VladSelikh]

Yes

[christian-bromann]

It seems like this is not supported by Firefox anymore, even though it was supported a while ago. We have a note to our command saying:

Note that using Puppeteer requires support for Chrome DevTools protocol and e.g. can not be used when running automated tests in the cloud. Find out more in the Automation Protocols section.

I think it makes sense to be clear about that this will only work when running Chrome tests locally.

Got it, thanks😉

I've found the solution of how I can access clipboard data in Firefox
I just needed to adjust Firefox caps in my config file:

{
    browserName: 'firefox',
    'moz:firefoxOptions': {
      prefs: {
        'dom.events.asyncClipboard.readText': true,
      }
    },
  };

...and then in tests just use:

const clipboardText = await browser.execute(() => navigator.clipboard.readText());
await browser.url(clipboardText);

Thanks for sharing this! I raised webdriverio/example-recipes#418 to make sure we eventually have better docs for this. Feel free to contribute 😉
