Set Database Extension fails with GatewayTimeout after restoring DB from .bacpac

Question

I am attempting to import a database via a .bacpac file which I have stored in blob storage.

I have created an Azure SQL serve, and followed the import steps described in the video attached: https://learn.microsoft.com/en-us/azure/azure-sql/database/database-import?tabs=azure-powershell

After completing, the DB is available in resources, however when I use the query editor I cannot see any of the DB tables.

Within my activity log, the "Set database extension" task has been repeating and failing every couple of minutes, with the error "The gateway did not receive a response from 'Microsoft.Sql' within the specified time period." Within the error JSON the properties are as follows:

"properties": {
"statusCode": "GatewayTimeout",
"serviceRequestId": null,
"statusMessage": "{\"error\":{\"code\":\"GatewayTimeout\",\"message\":\"The gateway did not receive a response from 'Microsoft.Sql' within the specified time period.\"}}",
"eventCategory": "Administrative"
},

Any help with this would be greatly appreciated
