RSelenium not working anymore on macOS with error Undefined error in httr call-CodePudding

I try to run a selenium server, connected to a firefox in MacOS. This had worked until I updated Java. I dont know what to do, and I cant use Docker cause I need to download some outputs from the website Im trying to scrape.

This is the verbose of the error:

CodePudding user response：

I have encountered this error myself before, and most likely this is caused by using the same port number during multiple attempts. Every time, the port number must be changed.

Also, if that fails, I highly recommend using the wdman package to manage your RSelenium server.

See my post here for an example usage of wdman:
