Hi All,

I am trying to set up jenkins with helm. The deployment works but I am running into a 403…

So the basic install is with these plugins:

```auto
  installPlugins:
    - azure-ad:476.vd1c42682ea_6a_  
    - azure-keyvault:251.vcfe31c013dc7

```

Controller:

```auto
controller:
  # -- Used for label app.kubernetes.io/component
  componentName: "jenkins-controller"
  image:
    # -- Controller image registry
    registry: "docker.io"
    # -- Controller image repository
    repository: "jenkins/jenkins"

    # -- Controller image tag override; i.e., tag: "2.440.1-jdk17"
    tag: '2.457-jdk17'

```

This lets me login and manage jenkins. after then installing:

> **[Pipeline](https://plugins.jenkins.io/workflow-aggregator/)**
>
> A suite of plugins that lets you orchestrate automation, simple or complex. See Pipeline as Code with Jenkins for more details.

Now when you try to configure the plugin you get this in the console:

Pressing save will get you this the oops page with an ID.  
This log ID will give you these logs:

```auto

Caused: javax.servlet.ServletException

```

After a few days of tryig to get this to work I am running out of options… Anyone got a usefull hint / tip to get this resolved?
