setting up build pod: Timed out while waiting for ServiceAccount/<service_account_name> to be present in the cluster

I am using helm charts to deploy Gitlab Runner into Kubernetes cluster. I want that the created pods when runner is triggered to have a costume services account instead of the default one. I did create role and cluster role and did the role bindings.

However, I am getting the following error when running a CI job

From Gitlab CI

runners:
  concurrent: 8
  name: initial-runner
  config: |
    [[runners]]
      [runners.kubernetes]
        namespace = "namespace_test"
        image = "registry.gitlab.com/docker-images/ubuntu-base:latest"
        service_account = "gitlab-runner"
  tags: base

rbac:
  create: false
  serviceAccountName: gitlab-runner

any ideas on how to solve this issue?

In my case, I forgot to give the "gitlab-runner" cluster role the right permissions on "serviceaccounts" resource.
