az webapp list is showing null values for siteConfig

I want to get list of all webapps where healhCheckPath is not nult. I tried az webapp list --query "[?not_null(siteConfig.healthCheckPath)].{Name:name, ResourceGroup:resourceGroup}" and az webapp list --query "[?siteConfig.healthCheckPath!=null].{Name:name, ResourceGroup:resourceGroup}" but the cli was returning empty array. I then ran the command az webapp list --query "[?name=='web_app_where_health_check_is_enabled']" and this returns one record but heathCheckPath was null but in reality health check is enabled for this specific app. Later I tried az webapp show -g <resource-group> -n <name> and this showed me the value for healthCheckPath. So the issue is with the list command. I can’t use webapp show command because I want to fetch all the webapps which meet specific conditions.

@junaidahmed92 This seems to be by design with an extra REST API call required to get the configuration for a web app, which the CLI is performing when running az webapp show. Here is a workaround you can use instead.

Bash

az webapp list --query '[].id' -o tsv | xargs | xargs -I{} bash -c "az webapp show --ids {} --query '[?not_null(siteConfig.healthCheckPath)].{Name:name,ResourceGroup:resourceGroup}'"

PowerShell

(az webapp list --query '[].id' -o tsv) -Join (" ") | %{Invoke-Expression "az webapp show --ids $($_) --query '`"[?not_null(siteConfig.healthCheckPath)].{Name:name,ResourceGroup:resourceGroup}`"'"}

@junaidahmed92 Looks like this is a limitation of the underlying REST API (Web Apps - List) where it doesn’t include siteConfig data. I will check with the concerning team for more insights.
