Commencez par src/Core/Services/MetadataProviders/SqlMetadataProvider.cs au niveau de PopulateObjectDefinitionForEntities et InitializeAsync, puis suivez l’échec jusqu’à src/Service/Startup.cs au niveau de PerformOnConfigChangeAsync. Reproduisez le scénario scale-to-zero d’Azure Container Apps avec Azure SQL et déterminez pourquoi l’initialisation à l’exécution échoue pendant le post-login timeout. La tâche est terminée lorsque la cause et une résolution vérifiée pour la première requête après le scale-up sont établies.
