error when env.reset(options={"config_file": config_file})

[yananchen1989]

hello, I encounter an error following the example of [Quick Walkthrough] part:

when executing obs, info = env.reset(options={"config_file": config_file})

there is error:

any advice to solve this ? thanks.

Hi @yananchen1989 This error is saying that playwright is trying to start a graphical browser interface in an environment that doesn't have one. Are you running this on a server by any chance? You can set headless=True here to stop playwright from opening a browser interface to proceed.

@oootttyyy thanks. it works.
