Azure Resource Manager (ARM) Import Databases (Bacpac) Error (Closed) - azure

Question

I am using ARM template to perform Import Azure SQL databases from bacpac files storing on my storage account.
However I am getting unexpected Bad Request error from Azure.
The same ARM template has been working fine just a few weeks ago.
When I try to do the Import Databases in the new Azure portal manually, I am also getting error from Azure, but they didn't specify the error detail.
I have tried for three different locations: Southeast Asia, North Europe and Central US but all have failed.
Below is my ARM template portion for database server and database import.

The error from Azure portal for my ARM deployment:
Any help or advice is appreciated!
Note: I have suspected this could be due to platform issue but there is no issue reported for the past few days on the locations I tried based on the
Azure status history

Answer 1

Verified with Microsoft Azure Support and they confirmed this is a platform issue.
Update:
The issue is verified resolved after Microsoft resolved the platform issue related to Import Database.
