bdk-flutter and payjoin-flutter integration error

[BitcoinZavior]

Using bdk-flutter with payjoin-flutter results in payjoin-flutter throwing The receiver sent an invalid response: proposed transaction outputs contain key paths

Tests pass when using bitcoin core in place of bdk-flutter.

Both bitcoin core and bdk-flutter integration tests are available here: https://github.com/LtbLightning/payjoin-flutter/blob/main/example/integration_test/bitcoin_core_full_cycle_test.dart

Steps to replicate: Follow the steps for setting up bitocoin node to run the integration tests: https://github.com/LtbLightning/payjoin-flutter?tab=readme-ov-file#build-and-run-code

Run the integration test https://github.com/LtbLightning/payjoin-flutter?tab=readme-ov-file#running-the-integration-tests
This will result in ResponseError { message: "The receiver sent an invalid response: proposed transaction outputs contain key paths" }
