When doing POST request from react frontend to mySQL backend, should the database automatically create “id” for every object? Because from some reason, the database doesn’t create “id” like this:

helloe friends
Getting error in chrome >inspect>console

I have in my MySQL Table e.g. 4 Entries.

Hey guys i explain to you my situation: i simply want to select one element from and list on my frontend and swap with with the element above it via an arrow up button.
