Help! Patch Request fails on bravo vision.

Hello everyone,

First of all, my name is Jib. I'm a doctor. And I'm interested in building an electronic health record app for my nursing home.

Here is my problem, I followed this tutorial exactly step by step, and everything worked well until the final part, Patch Request. 
(the tutorial I followed--> https://www.youtube.com/watch?v=4o5qHrX-kKU)

when I test the app in bravo vision and submit the form in the editing part of the data, it states an error alert, and I don't know why (because I've followed the tutorial exactly step by step😭)

I tried to fix it every way I could (check the API in the data section works fine, check the tag in the Figma file seem like nothing is wrong, and data binding is exactly like in the tutorial.)

I don't know how to share my project here. Unfortunately, I can only send it by email. (Is there anyway else to send my project to you, please let me know)

Please help. It has been very frustrating for almost three days now.😫😭
