Everytime I install arcnetworking extension, I fall into following error. If I provide the k8sRuntimeFpaObjectId argument then it says unrecognized arguments: --k8sRuntimeFpaObjectId

`(ExtensionOperationFailed) The extension operation failed with the following error: Error: [ InnerError: [Helm installation failed : Unable to render the Helm chart with the provided config settings and config protected settings : Recommendation Please check if the values provided to the config settings and the config protected settings are valid for this extension type : InnerError [execution error at (arcnetworking/templates/config.yaml:56:13): k8sRuntimeFpaObjectId parameter is required]]] occurred while doing the operation : [Create] on the config, For general troubleshooting visit: , For more application specific troubleshooting visit: please reach out to Microsoft tech care if you need help with debugging the problems with your extension resource.

    Hello !

    Thank you for posting on MS Learn Q&A.

    The issue is that k8sRuntimeFpaObjectId is not a top-level Azure CLI argument. It must be passed as an extension config setting either through --config-file / --config-settings-file or as key=value via --config-settings. The az k8s-extension create command supports config settings files and if you look into the doc below k8sRuntimeFpaObjectId being supplied inside config.json not as --k8sRuntimeFpaObjectId.

    https://learn.microsoft.com/en-us/cli/azure/k8s-extension?view=azure-cli-latest

    You should do like below :

    az extension add --upgrade --name connectedk8s
az extension add --upgrade --name k8s-extension

    I recommend that you use the latest Azure CLI with the latest connectedk8s and k8s-extension extensions before creating Arc Kubernetes extensions.

    Then get the object ID and place it in a config file:

    objID=$(az ad sp list --filter "appId eq '<app_id>'" --query "[].id" -o tsv)

    {
 "k8sRuntimeFpaObjectId": "<object-id>"
}

    And install like this:

    az k8s-extension create \
 --cluster-name <clusterName> \
 --resource-group <rgName> \
 --cluster-type connectedClusters \
 --extension-type microsoft.arcnetworking \
 --name arcnetworking \
 --config-file config.json

    You can also pass it inline instead of using a file:

    az k8s-extension create \
 --cluster-name <clusterName> \
 --resource-group <rgName> \
 --cluster-type connectedClusters \
 --extension-type microsoft.arcnetworking \
 --name arcnetworking \
 --config-settings k8sRuntimeFpaObjectId=<object-id>

    The reason your 2nd attempt fails is that --k8sRuntimeFpaObjectId is not a recognized CLI parameter for az k8s-extension createthe command only accepts generic config inputs such as --config-settings and --config-file.
