1.7 to 2.5 field not found, node: entryPoint

Traefik Traefik v2
1

Hey folks, currently working to update traefik from 1.7 to 2.5 for Kubernetes 1.22 support. After changing my ingress charts to the 1.22 spec, and updating the traefik image that gets pulled, I get the following error while the traefik pod is starting up:

command traefik error: field not found, node: entryPoint

This is happening when the pod is starting so I am unable to actually bash into the pod and view the toml file. Any guidance here would be greatly appreciated.

Above is the actual docker describe of the traefik pod.

          securityContext:

Oh I lied, I found the toml in a configmap helm chart.

   defaultEntryPoints = ["http"]

    [entryPoints]
      [entryPoints.http]
      address = ":12000"

      [entryPoints.api]
      address = ":13000"

      [entryPoints.ping]
      address = ":14000"

      [entryPoints.metrics]
      address = ":15000"

    [file]
    directory = "/config/dynamic"
    watch = true

    [kubernetes]
    ingressClass = "data-service-fabric"

    [ping]
    entryPoint = "ping"

    [api]
    entryPoint = "api"

    [metrics]
      [metrics.prometheus]
      entryPoint = "metrics"

Hello,

Have you checked all the content of dynamic.yml with the JSON schema of the dynamic configuration?
