I recently deployed selenium grid 4 on my kubernetes cluster using the helm chart https://github.com/SeleniumHQ/docker-selenium/blob/trunk/charts/selenium-grid/values.yaml. Everything works fine but when video recording is enabled, the sidecar video container records sessions with a null value. the logs of the container are as follows
