Cannot launch two chromium instances in single docker container

[Terrible59]

Hi! I'm having an issue with running several bots in one docker container simultaneously. The first bot starts successfully, but when I'm trying to start another bot this error pops up:

(node:4057) UnhandledPromiseRejectionWarning: Error: Failed to launch the browser process!
