How to use AWS S3 REST API ListObjects v2 with multiple parent child bucket directories

Question

What am I missing here?

I'm able to list objects with no problem using the AWS CLI and this command:

AWS s3 ls s3://bucket.mycompany.com/parent-dir1/parent-dir2/

But using the REST API via Postman, an equivalent request returns an empty response.

• Tool: Postman

• Method: GET

• Auth:

• Headers:

  • I've tried with no headers and with x-and-content-sha256 UNSIGNED-PAYLOAD

  • The message says "This is a duplicate header and will be overridden..." when I try to use this header

• Response:

• Status 200 but response is empty(There are MANY files in parent-dir2).
