Relevant information

I am trying to build a custom connector using the connector builder and this is a asynchronous stream as it requires the creation of the job, polling and download.

I have tested it and it it works for the creation and polling part but fails in the download part

Creation response :

Polling response :

And this is the download link : https://branch-exports-web-usw2.s3.us-west-2.amazonaws.com/branch_agg_async_api/y%3D2025/m%3D11/d%3D20/app_id%3D644074824343244968/job_id%3D72c6336b-0795-41cb-a273-4b500fe52032/task_id%3D0/644074824343244968-2025-11-20-eo_install_eo_click-branch_agg_async_api-db1bd789b63c60fd0f44a91f19d0f20ca6cb29fdd56bc9b7e1a965b2d6bd4ed3-IoNlDB-0.csv.gz?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20251120T024935Z&X-Amz-SignedHeaders=host&X-Amz-Expires=604800&X-Amz-Credential=AKIA3HUFQARVSRBPVFYG%2F20251120%2Fus-west-2%2Fs3%2Faws4_request&X-Amz-Signature=cdec43365f5409e09d3c4e8bc08f229d00223a4202e5bd197e6eb944bc3c1b8c

The download link is a file which is a csv.gz which i have attached below and this is the config I made in the download panel, where http response = gzip and unzipped data format is CSV.

I keep getting the error below

sample csv.gz file :
644074824343244968-2025-11-20-eo_install_eo_click-branch_agg_async_api-db1bd789b63c60fd0f44a91f19d0f20ca6cb29fdd56bc9b7e1a965b2d6bd4ed3-IoNlDB-0 (1).csv.gz

Is there a way where the file is not read and just downloaded to the target airbyte destination
