[🐛 Bug]: Selenium Grid is not starting the node containers

What happened?

I configured selenium grid in a kubernetes cluster via helm specs. I did the required changes based in what is required for running Selenium Grid dinnamic so I configure the config.toml as a ConfigMap (as I pasted in the command section)

I made a request and the hub received it as the log shows:

But no container was started and the requsition timeout. I already figured out how to run selenium grid in a non-dinamic way, but no success so far in a dinamic way Do anyone knows if this configuration is working?

Command used to start Selenium Grid with Docker

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ template "seleniumGrid.hub.fullname" . }}-configmap
data:
  config.toml: |
    [docker]
    configs = [

        "seleniarm/node-chromium:101.0", "{\"browserName\": \"MicrosoftEdge\"}"
        ]
