    Hi nathan-verghis ,
    Thanks for the follow-up.

    Since the issue persists even after trying the available workarounds and there's no clear indicator from the Dataflow logs, the best next step would be to raise a support ticket with Microsoft for deeper investigation. If you've already raised a support request, please consider sharing any insights or resolutions provided by the support team here, it would be helpful for others facing the same issue.

    Also thanks to miguel and Ilgar_Zarbali for addressing this and sharing your valuable insights.

     

    Best Regards,
    Vinay,
    Community Support Team.

Hi nathan-verghis ,

Thank you for reaching out and for sharing the details of your architecture and observations.

The error code 20302 in Fabric is a generic message that does not provide much detail, which makes it difficult to troubleshoot directly. Based on the information provided and known patterns with similar cases, this error can sometimes occur due to several underlying reasons.

 

One common cause relates to how Dataflow and Lakehouse connections are configured and managed, especially when different users create or modify the connections. When a Dataflow is created or connected to a Lakehouse using one user’s credentials, another user accessing or modifying the Dataflow may encounter errors if their permissions or authentication context differs from the original creator. Reestablishing connections or using a shared service account can sometimes mitigate this.

There have also been reports of intermittent network issues affecting Dataflow runs. While your data ingestion from Snowflake into the Bronze layer works consistently, the failure in the subsequent Dataflow could be related to transient network problems that are not always surfaced clearly in error messages.

Another possibility is resource limitations, especially when working with larger Dataflows or complex transformations. If the Dataflow exceeds available system resources during execution, it may fail without detailed logging.

To investigate further, please check the detailed error logs in the Dataflow’s refresh history. Sometimes, nested messages within the job history may provide additional clues beyond the generic 20302 error. If any specific error messages are visible there, please share them, that would help to narrow down the root cause.
