Unfortunately, quill would need to be updated to the newest version of the ICP mono repo, I made a PR for that ([Bump IC version to 00b04a892dfb2fee1459f1de9d4a731aa04f1ca3 by aterga · Pull Request #259 · dfinity/quill · GitHub](https://github.com/dfinity/quill/pull/259)) but it got stuck on some build issues, and I didn’t have time to debug that yet. The advantage of DFX is that it’s always up to date with the latest SNS API and features, and I recommend using DFX in interactive mode to submit SNS proposals more easily (no need to hand craft Candid payloads). I’m working on a documentation page for describing all of this, but it’s still a draft. Please let me know if DFX can unblock you. --- _[View the full topic](https://forum.dfinity.org/t/genericnervoussystemfunction-error-nervoussystemfunction-must-have-a-topic/42024)._
