What happened?

I deployed Azure Web App to run dab and it was okay for early version in 2023 I remembered. However it is failed with the up-to-date version. How do I fix it, need new startup command or other more configuration

The startup command was dotnet Azure.DataApiBuilder.Service.dll --ConfigFileName /App/config/dab-config.json for azure-databases/data-api-builder:latest

Version

latest

What database are you using?

Azure SQL

What hosting model are you using?

Which API approach are you accessing DAB through?
