Summary of Changes

Hello @krishnamd-jkp, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a subtle bug where an empty filter string was inadvertently being sent in HTTP list object requests, which could lead to unexpected or erroneous behavior from the API. The core change introduces a safeguard to omit the filter parameter entirely if it's empty. To ensure the robustness of this fix and prevent regressions, a dedicated integration test case has been added to verify that listing objects without any filter functions correctly and returns all expected results.

Highlights

• HTTP Request Filtering: Implemented a conditional check to prevent an empty filter string from being passed in HTTP list object requests, resolving potential issues with the underlying API.
• Integration Testing: Added a new integration test case specifically to validate the behavior of listing objects when no filter is provided, ensuring the fix works as expected.

Code Review

This pull request addresses a bug where an empty filter string was being sent in a list objects request, which is not supported by the backend API. The fix correctly adds a check to only apply the filter if the string is not empty. This is a clean and effective solution. The addition of a new integration test case for a query without a filter is a great improvement, as it verifies the fix and increases test coverage. The changes are correct and enhance the robustness of the client.
