Zhenghong Bao, I recently built a solution using paperclip as send keys made the browser hang with large amounts of text which caused the automation to time out and fail however, one thing you need to mindful of when using paperclip, is it doesn't paste text to a textarea if the browser is in headless mode.

When I ran the solution in headless mode, the text wasn't being added, but as Selenium found the textarea, the automation didn't consider it as an exception and continued without reporting it.

I only found out when the team raised a ticket for the missing text.

Ive moved it to its own server just to be on the safe side. I wonder if another solution causing a conflict.

Ive since switch to java to post large text.
