Description

As mentioned in Ticket #4754 you removed the Element::getSource Method with Craft 3.3, but it is still in the docs: https://docs.craftcms.com/api/v3/craft-base-element.html#public-methods

Steps to reproduce

1. Go to https://docs.craftcms.com/api/v3/craft-base-element.html#public-methods

Thanks for reporting that! We’ve been having issues with the API doc generation for the past few weeks, and I finally had a chance to track the culprit down and get the API docs updated. So getSource() is no longer listed now.
