Unable to deploy .NET 7 Isolated via App Service Build Service

[scale-tone]

Trying to deploy a .NET 7 Isolated project from git sources using Deployment Center (App Service Build Service). The build succeeds, the log says that all files were successfully created and copied. But the function does not appear in the list of functions and cannot be triggered (the URL returns 404). When downloading the app's contents, the downloaded ZIP-file doesn't contain the binaries, only an empty host.json file.

Build logs:

Command: "C:\home\site\deployments\tools\deploy.cmd"

Omitting next output lines...
Finished successfully.

Repro steps:

• Go to Azure Portal and create a Function App instance - North Europe, .NET 7 Isolated, Windows, Consumption tier.
• Go to the newly created Function App's page.
• On the Configuration/General Settings tab set 'Basic Auth Publishing Credentials' to 'On' (otherwise App Service Build Service cannot be configured).
• Go to Deployment Center tab.
• Configure deployment from an external git repo (you can use this test one, for example) using the built-in build (App Service Build Service).
• Wait until the build finishes successfully.
• Observe that the function doesn't get picked up.

Note that it works fine for .NET 6 InProc (last time I checked).

Is there anything that can be configured to make it work?
