Hi [@Kazuaki Mizota ] ,
Welcome to Microsoft Q&A platform and thanks for using Azure services.
As I understand from the error, you are facing Error SQL72014 and Error SQL72045 when trying to import .bacpac to Local server.
Error SQL72014 which is requesting to enable contained database authentication on the SQL Server instance.
In order to restore a contained database coming from Azure SQL Database into an on-premise SQL Server instance the "contained database authentication" property must be enabled.
Could you please to execute below command and see if this helps in your case:
sp_configure 'contained database authentication', 1;
GO
RECONFIGURE;
GO
