Cannot Install/Delete Web App Site Extension utilizing Azure SDK for Python

[is300fanatic]

• Package Name: azure-mgmt-web
• Package Version: 7.0.0
• Operating System: Windows
• Python Version: 3.10.0

Describe the bug When creating a webclient through the WebSiteManagementClient() and utlizing to invoke web_apps.begin_install_site_extension({required params}) it always returns 400 "Bad Request"

I've tried with many different Site extensions on a few separate app services - the request is making it to the endpoint but there is no message in the payload indicating what this issue is within the request nor does the Request URL look malformed in any way when debug logging.

Request URL: https://management.azure.com/subscriptions/{Masked}/resourceGroups/{Masked}/providers/Microsoft.Web/sites/{Masked}/siteextensions/AppDynamics.WindowsAzure.SiteExtension.4.5.Release?api-version=REDACTED

(Masked Sensitive values within the Request URL above.)

To Reproduce Steps to reproduce the behavior:

1. install SDK Package
2. find an Azure Webapp to do a fresh install of a SiteExtension against.
3. create Webclient from SDK package utilizing WebSiteManagementClient()

webclient = WebSiteManagementClient(credential=credential, subscription_id=subscription_id, api_version=apiVersion)

4. invoke installation of Site Extension to targeted WebApp :

install_site_ext = webclient.web_apps.begin_install_site_extension(resource_group_name=resourceGroupName, name=siteName, site_extension_id=site_ext_id)

Expected behavior Site Extension gets installed successfully and reports back the status within the response.

Screenshots

Additional context The begin_install_site_extension just doesnt work - I can see the log App Service side but fails to install the extension completely with no additional data as to why. - [exception posted in screenshot]

when issuing a delete_site_extension it does remove the extension from the Service but still returns a bad request in the response - only way to know it was removed is manually checking the service or targeting the service with the SDK to check for the Extension there after.
