I am receiving this error while doing the Data Flow Data Preview in Debug.

User's image

It's not consistent. Sometimes it will appear at the first step, sometimes somewhere along the flow, for previewing data of as simple as a Select step.

We have checked the source and all other connectors, redid everything however the issue still remains unresolved.

Any guidance is highly appreciated.

    The error in Azure Data Factory suggests an inconsistency in fetching or streaming data for preview. This can be due to transient network issues, hitting service limits, or issues with the source data. Ensure there are no connectivity issues on your end and that you're not exceeding any service quotas. Clearing your browser cache, trying different browsers, and refreshing metadata can sometimes solve these glitches. Additionally, enabling logging can provide more insight. If none of these solutions work, consider recreating the affected resources or reaching out to Azure Support for more specific assistance.
