Connection to the SQL EndPoint of the Dataverse shortcut ok but error when running the pipeline

[vivien57]

Hello everyone,

I'm having a problem that I don't understand.

I have a Data Pipeline with a copy activity that takes the SQL EndPoint of a Lakehouse (which is a shortcut on a Dataverse model) as its data source.

I configure the connection correctly and I'm able to connect and display the data from the tables in preview.

However, if I run the pipeline I get the following access error

Here are the details of the message :

ErrorCode=SqlFailedToConnect,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Cannot connect to SQL Database. Please contact SQL server team for further support. Server: 'xxxxxxxxxxxxxxxxxxxxxx-yyyyyyyyyyyyyyyyy.datawarehouse.fabric.microsoft.com', Database: 'DE_LH_SHORTCUT_DYNAMICS', User: ''.

What seems strange to me is that in the error message returned, the user is empty (in red in the error message).

Do you have any idea?

Thanks in advance for your help,

Have a nice day,

Vivien

Hello,

I've just tried not using the EndPoint via the Dataverse connector and it doesn't work, for another reason...

Hi @vivien57 

Based on the error message, here are some possible reasons and some suggestions from me:

The error message says that the user is empty. This may be because the authentication information is not passed correctly. Please double-check the connection settings and ensure that the correct user credentials are provided.

The error message also suggests that you check the firewall settings for the SQL database. Make sure the firewall allows access, you may need to add the IP address of the data factory to the allow list in the SQL database firewall settings.

The error message mentions network-related or instance-specific errors. Make sure there are no network issues blocking the connection. This may include checking whether the SQL server is accessible from your network and whether there are any network policies blocking the connection.

Also, you can verify whether the SQL server is configured to allow remote connections.

I hope this content is helpful to you.

Hello @Anonymous 

Thank you for your feedback.

For the first point, I checked and tested with authentication via an organisation account and via a Service Principal. Nothing works, the result is an identical error.

From a firewall and network point of view, we don't see anything strange either. The EndPoint has been reached on port 1433.

What I find really strange is that in the error message the user is empty...

do you have any other ideas?

Thank in advance,

Have a nice day,

Vivien
