# Stale APIService Causing API Discovery Failures while running kubectl

## Problem

Clients such as `kubectl` (v1.22+), `client-go`, and Dynatrace components experience API discovery failures, with repeated error messages like:

{% tabs %}
{% tab title="kubectl" %}

```javascript
couldn't get resource list for packages.operators.coreos.com/v1: the server is currently unable to handle the request
```

{% endtab %}
{% endtabs %}

## Environment

* Platform9 Managed Kubernetes
* kubernetes v1.23 and Higher

## Cause

A stale/deprecated `APIService` object (`v1.packages.operators.coreos.com`) still exists in the cluster and references a Kubernetes Service (`v1-packages-operators-coreos-com`) in the `pf9-olm` namespace, which no longer exists. This results in a `ServiceNotFound` condition, which newer clients treat as a hard error during API discovery.

## Resolution

Backup the APIService definition (for audit purposes):

{% tabs %}
{% tab title="kubectl" %}

```javascript
kubectl get apiservice v1.packages.operators.coreos.com -o yaml > broken-apiservice-backup.yaml
```

{% endtab %}
{% endtabs %}

Delete the stale/deprecated APIService:

{% tabs %}
{% tab title="kubectl" %}

```javascript
kubectl delete apiservice v1.packages.operators.coreos.com
```

{% endtab %}
{% endtabs %}

## Additional Information

The issue is not observed in `kubectl` versions older than v1.20.1 because older versions of `kubectl` and `client-go` handle unavailable or misconfigured `APIService` resources more gracefully—typically by logging warnings instead of failing or blocking discovery entirely.
