error with chromedriver 2.28.455517 mac os in cloud

Error when trying to use wdio-screenshot. I believe that it results in the driver crashing because I get no more data back from the driver after the error occurs.

OS: Mac 10.12 (or any mac os) CHROME DRIVER: chromedriverVersion=2.28.455517 Chrome Browser version: any version

ERROR: "message: 'unknown error: unhandled inspector error: {"code":-32000,"message":"Unable to capture screenshot"

• issue is only on mac
• Issue is only in cloud service (sauce labs and crossbrowsertesting.com are the ones I've tried)

On my local machine it works fine and I also have the same setup: OS: Mac 10.12 (or any mac os) CHROME DRIVER: chromedriverVersion=2.28.455517

I'm not sure how the "cloud" part comes in to play here.

NOTE: I have not yet tried other versions of chromedriver because I myself don't have the ability to update these driver on the cloud service.

NOTE: webdriverio "saveScreenshot" command works fine in this scenario. The problem is specific to wdio-screenshot.

I have this issue also with saucelabs. That's why I stopped testing chrome on MacOS in #74.

But I have no idea what's wrong there. I can confirm that it works on my own Mac without any problems...

Ok. Do you think it is an issue with the temporary directory that it being created? Strangely enough in crossbrowsertesting.com ("chromedriverVersion":"2.29.461585) It will take 4 or 5 screenshots successfully before crashing. If you can at least give me a clue of what to try I will troubleshoot it.

Thanks!

I don't think so. The capturing of the screenshot fails on the selenium side.

Just found this: https://bugs.chromium.org/p/chromedriver/issues/detail?id=1802&q=%22Unable%20to%20capture%20screenshot%22&colspec=ID%20Status%20Pri%20Owner%20Summary

I close this, as this isn't a wdio-screenshot issue. Hopefully this gets fixed soon.
