UserErrorSourceNotSeekable

Hi Naveen_Yedla333, 

This is a fairly clear error message, and it even includes a recommended workaround - I love to see the Fabric error messages getting better. 

That error means the pipeline is trying to treat your HTTP source like a "seekable" file (able to jump around inside it), but most HTTP endpoints don’t allow that. A direct copy won’t work because the service needs to re-read parts of the file to process it.

You’ll need to stage the file before loading it:

1. Create a first Copy Activity that downloads the ZIP file from HTTP and writes it to a staging location like a  Lakehouse.

2. Create a second Copy Activity that reads the staged file and loads it into your target (using the same settings you already had).

If you found this helpful, consider giving some Kudos. If I answered your question or solved your problem, mark this post as the solution.
