I successfully fixed issue #7621 in the OpenHands repository, which was about the "start from scratch" button resulting in a "no query provided" error.

Summary of Changes

1. Root Cause Analysis: The issue occurred because the useCreateConversation hook was throwing an error when no query was provided, but the "Start from scratch" button was designed to create a conversation with an empty query.

2. Solution Implemented:

   • Added an allowEmptyQuery parameter to the useCreateConversation hook to bypass the validation check when explicitly starting from scratch
   • Updated the CodeNotInGitHubLink component to use this new parameter when the "Start from scratch" button is clicked
   • Created comprehensive tests to verify the fix works correctly

3. Testing:

   • Created unit tests for both the useCreateConversation hook and the CodeNotInGitHubLink component
   • All tests passed successfully, confirming the fix works as expected

4. Pull Request:

   • Created PR Fix: "start from scratch" button results in a "no query provided" error #7622 with the title "Fix: 'start from scratch' button results in a 'no query provided' error"
   • The PR description includes details about the changes and mentions that it fixes issue [Bug]: "start from scratch" button results in a "no query provided" error #7621
   • Added the requested link for @neubig to continue refining the PR

The fix was minimal and focused on the specific issue, allowing users to start from scratch without encountering the error message. The implementation follows the repository's coding standards and includes proper test coverage.
