Binder error status 415

Hi! I have a problem with Binder. I try to enter data into the form and it’s return error with status “Unsupported Media Type”. I tested my backend app with Postman and everything works fine. Why binder has a problem with convert data to JSON? Any ideas? Thanks for help.

Try setting a breakpoint on UserService:55 and see if you can see anything odd there

On UserClient? User is null but I don’t know why…

I can change actual records but I can’t enter new

Maybe you can start on UserForm:64 and dig your way down to see why
