What happened?
I was getting an error message Unable to execute request for an existing session: Unable to find session with ID: and saw a possible solution described in SeleniumHQ/selenium#9988 and followed a hint in the ticket to try running the 4.1 prerelease.
when staring the hub and nodes I get errors similar to this for each chrome node:
java.io.IOException: Port 5502 already in use
I am running selenium grid under podman 3.3.1, which I know is not supported. The startup command podman-compose is the podman equivalent to docker-compose
Is there a difference in how ports are defined or specified with the prerelease, either in docker-selenium or in selenium proper?
Command used to start Selenium Grid with Docker
podman-compose --project-name grid -f container-compose.yml up --build --remove-orphans -d
