[BUG] Create Project - Duplicate From Bounty: Impossible complete creation with different Reward Type

[rknearn-qa]

Summary

When duplicating a Bounty listing with a Fixed Payment type and Additional Prize, then converting it to a Project listing with a Range payment type, the system returns a 400 Error, preventing creation. This blocks Sponsors from efficiently reusing existing Bounty listings to create Projects, which is a key workflow for listing management.

Preconditions:

• User is registered as a Sponsor (https://nearn-app-staging.onrender.com/t/userqa/).
• A Bounty listing is created with Additional Prize for Fixed Payment type.

Steps To Reproduce

1. Open the original Bounty listing.
2. Duplicate the listing.
3. Change the listing type from Bounty to Project.
4. Change Payment Type from Fixed to Range.
5. Configure a valid Range Prize.
6. Attempt to create the Project listing.

Actual Result:

Failed Listing example - https://nearn-app-staging.onrender.com/dashboard/listings/project-submission/edit/

• The listing creation fails with HTTP 400 Error.
• Listing is not created, and no success message is shown.

Expected Result:

• Users should be able to duplicate a Bounty listing, change the type to Project, modify the reward type, and successfully create the new Project listing.

Special Notes / Possible Root Cause:

- Backend may be validating reward type inconsistently during duplication.
- Certain fields (Additional Prize / Range) might not be properly mapped between Bounty and Project types.
- The 400 error indicates a request validation failure, likely due to incompatible data being sent to the API.

Workarounds:

• Currently, no reliable workaround exists other than creating a Project listing from scratch.

Reproducibility Rate: Always (10/10)
