Selenium WebDriverException: The expected mouse "id" must be mapped to an InputState whose subtype is undefined, received by: pointerMove
I have a problem with Selenium that I cannot figure out about. Also, I cannot find much information on this issue via Google.
My Selenium script does the following steps:
- Log into Facebook.
- Go to the list of friend suggestions.
- Scroll down a few times (to load more offers).
- Submit all sentences one by one on the console and ask the user if they should add a friend.
On confirmation, a chain of actions is created that navigates to the proposal in question, and then the add button is clicked.
But chaining doesn't work. I am getting the following error:
Potential friend name: 'John Doe'
Social context: 'Max Mustermann und 3 weitere gemeinsame Freunde'
Traceback (most recent call last):

I am using the latest version of Selenium:
C:\Users\Robert>pip show selenium
Name: selenium
Version: 3.3.1
And I have Firefox 52.0.1 with geckodriver v0.15.0.
Update: . A quick test showed that the same script works flawlessly with Chrome Webdriver.
Update 2: This issue in the Selenium bugtracker on Github may be related: https://github.com/SeleniumHQ/selenium/issues/3642 p>
