I am currently running my Protractor tests on SauceLabs and BrowserStack and have FileDetector configured so that I can run tests that involve uploading files.
I am getting an error that says 'Uploading directories is not supported" when I try to use sendKeys() to write a message in a textarea. I do not get this error when FileDetector is not included in the page. To clarify, I am not doing any uploading at all when this error occurs - just trying to add text to a textarea.
Also, sendKeys does work in certain instances but not in others.
Thanks for your help!
