I have completed the dashboard tutorial on the nextjs website. When I update an invoice with new field values they update as expected. However when trying to update them to values that have been stored before, the record does not update but also doesn't show any errors. I'm wondering if this is by design somehow and I am missing it or how to fix it if not.

I even tried replacing my entire code with https://github.com/vercel/next-learn/tree/main/dashboard/final-example and the problem persisted. My database is deployed to vercel as per the tutorial.
