Unknown field "spec.template.spec.containers[0].securityContext.fsGroup"

[chaich-pcs]

While deploying Tyk Control Plane using a Helm Chart 3.0, I get a warning:

Unknown field "spec.template.spec.containers[0].securityContext.fsGroup"

I am deploying on Kubenetes version 1.32.8, which is a tested version
https://tyk.io/docs/developer-support/release-notes/helm-chart/

Checking the schema of Deployment object, it does not contain a field called "fsGroup" in "securityContext"

kubectl explain deployment.spec.template.spec.containers.securityContext

As I did not change any security context configuration regarding fsGroup, I looked at the values in the charts, it seems to have come from the configuration for Tyk Pump

    # containerSecurityContext values for bootstrap containers
    containerSecurityContext:
      runAsNonRoot: true
      runAsUser: 1000
      fsGroup: 1000
      allowPrivilegeEscalation: false
      privileged: false
      readOnlyRootFilesystem: true
      seccompProfile:
        type: RuntimeDefault
