app service: siteConfig.http20ProxyFlag not recognized

[isak1080]

Resource Type

Microsoft.Web/sites

Api Version

2022-09-01

Issue Type

Missing property(s)

Other Notes

The property that controls the setting HTTP2.0 Proxy (under Configuration --> General Settings for an app service) incorrectly gets a warning when deploying the .bicep file:

Warning BCP037: The property "http20ProxyFlag" is not allowed on objects of type "SiteConfig". Permissible properties include...

However, after deploy, the setting is indeed set correctly.

Note that this setting is currently only available on Linux. It is needed when hosting gRPC services in azure: https://github.com/Azure/app-service-linux-docs/blob/master/HowTo/gRPC/use_gRPC_with_dotnet.md
