Hi @skarimulla2026 ,

Thanks for reaching out to us on Microsoft Fabric Community Forum!

The error you are seeing points to an issue with the Power Query steps or a mismatch between how the data is accessed in Power BI Desktop versus the Service. This is often related to gateway or credential differences.

Here are a few things you can check:

• Make sure the correct gateway is selected and running, especially if you are pulling data from on-premises or web sources.
• Go to the dataset settings in Power BI Service and double check that your credentials are up to date for all connected data sources.
• Take a look at your Power Query steps and ensure there are no hardcoded values (like file paths or URLs that might differ in the Service).

Refer the community thread that discusses this error and provides some troubleshooting tips:

Hope this resolves your query.If so,consider accepting it as solution.

Pallavi.
