A ‘Send Keys’ and ‘Form’ failure means there is a problem with that action. Both of these actions are important for filling out input fields such as login, payment and shipping details.
So why are you getting this failure message? Here are a few reasons starting from most common to least common:
Change in Selector
The most likely cause of this failure is the select you are evaluating has changed. An easy way to identify this is to navigate to the page with the failure on your site and paste the selector into the Dev Tools to check if it is picked up. If nothing is identified then we would recommend changing the selector to something else.
If your selector is present but you are noticing occasional failures on the ‘Send Keys’ your selector might not be reliable. For example if the selector is located on a button within a pop-up or a form it may not appear or not load correctly. If this is the case selecting something more reliable is likely to solve the failure.
