Is it possible to use an sql endpoint in fabric in Data API Builder?

[Narming1868]

Hi I'm trying to access a SQL Table in Fabric from DATA API Builder. But when I start dab with the configuration I receive the error
Azure.DataApiBuilder.Service.Exceptions.DataApiBuilderException: Cannot obtain Schema for entity TimeBookings with underlying database object source: dbo.calendardata_test_v2 due to: A server name like tcp:SERVERNAME.datawarehouse.fabric.microsoft.com,1433 is not allowed? Is my connect string wrong or does this not work.
Thanks for your help.

is there a specific error code included with that message? Are you also connecting from DAB to DW with a managed identity?

Hi, sorry for the late answer I was out of office last week. First of all
Currently (for testing) I try to run DAB on my Local Computer so now managed identity yet. I attached the config file.
dab-config.github.json

There is no specific error code
The full exception looks like this:
fail: Azure.DataApiBuilder.Service.Startup[0]
Unable to complete runtime initialization. Refer to exception for error details.

Thanks for your help.

You will want to remove the tcp: prefix from the connection string, that is not supported by Fabric warehouse. Also the database-type should be dwsql.
The config should look something like this:

  "data-source": {
    "database-type": "dwsql",
    "connection-string": "Server=SERVERNAME.datawarehouse.fabric.microsoft.com;Initial Catalog=dabtest;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;Authentication=Active Directory Default;"
  },
