When you use KubeKey to install add-ons, you put the add-on information (Chart or YAML) under the `addons` field in the configuration file (`config-sample.yaml` by default). If the add-on configuration is provided as a YAML file, in some cases, you may see an error message similar to this during the installation:
```bash
Error from server: failed to create typed patch object: xxx: element 0: associative list with keys has an element that omits key field "protocol"
```
This is a [known issue of Kubernetes itself](https://github.com/kubernetes-sigs/structured-merge-diff/issues/130), caused by the flag `--server-side`. To solve this issue, do not add your add-on in the configuration file. Instead, you can apply your YAML file after KubeSphere is deployed. For example:
```bash
kubectl apply -f xxx.yaml # Use your own YAML file.
```
