Error refreshing Dataflow Gen2 with CI/CD preview

[steve-james-hcc]

I created a set of Dataflow Gen2s with CI/CD preview in a new Fabric workspace yesterday. The dataflows ingest data from an on-prem SQL Server DB using the on-prem gateway and write the data to a SQL Database (preview) in the same workspace. Yesterday, the dataflows were refreshing fine, in a matter of minutes. Today, they all fail after a few seconds with the following error message:

There was a problem refreshing the dataflow: 'Something went wrong, please try again later. If the error persists, please contact support.'. Error code: 104206.

Furthermore, if I add a new Dataflow Gen2 with CI/CD preview, I get the following error message when attempting to connect a query in the dataflow to a destination table in my SQL Database (preview):

An exception occurred: Downstream service call to url 'https://api.powerbi.com/powerbi/globalservice/v201606/clusterdetails' failed. (Session ID: e8526907-bea1-4efb-aee2-2c4ad57897df, Region: uk)

Thanks @V-yubandi-msft .

I'm not using that tile to add the Dataflow Gen2 (CI/CD preview). I'm using the standard Dataflow Gen2 tile, then selecting the option to enable CI/CD preview in the resulting dialog box:

Having said that, I guess I'm encoutnring a preview bug. I'll revert to the non-preview version.

Hi @steve-james-hcc ,

Thank you for contacting the fabric community.

Hear you're encountering issues with your Dataflow Gen2 (CI/CD preview) refreshes in Microsoft Fabric. The errors you're experiencing, including error code 104206 and the downstream service call failure, are indicative of known issues within the platform.

1.  The Dataflow Gen2 (CI/CD preview) feature is currently not available for public use. Attempting to use this feature may result in an upgrade dialog box requesting a paid Microsoft Fabric Capacity. It is advisable to avoid using this feature until it is officially supported.

FYI:  Known issue - New tile for Dataflow Gen2 (CI/CD, preview) isn't yet supported - Microsoft Fabric | M...

Workaround:Since the Dataflow Gen2 (CI/CD preview) is not yet available for public use, it is recommended to avoid using this feature until its official release.
Instead, manually deploy Dataflow Gen2 in each workspace rather than utilizing CI/CD.

2.

An exception occurred: Downstream service call to url 'https://api.powerbi.com/powerbi/globalservice/v201606/clusterdetails' failed. (Session ID: e8526907-bea1-4efb-aee2-2c4ad57897df, Region: uk)

This pertains to the Dataflow Gen2 (CI/CD preview) feature in Microsoft Fabric. As this feature is not yet publicly available, using it may lead to errors.
