I'm making a POST function but I'm getting an error. I am getting "HTTP Status 400 – Bad Request" error in console. In the simulator, it says "Something went wrong. Please try again later" on the screen. I don't understand where I am making the mistake. I need to fix this error urgently. Could you help?

App registers the user to the server but still gives an error. When I press the register button, the user registers, but the application crashes.
After the application crashes, xcode displays the following screen.
It shows the error is here

How can I get rid of the app crashing?
There is a register screen I created to register the user to the app, but I cannot register the user. In xcode console it says "statusCode should be 2xx, but is 500"
Where am I doing wrong? Could you help?

Xcode keeps giving me the error "Expected to decode Array but found a dictionary instead". I don't understand what it mean here. More precisely, I did not understand what to do. I used the same code to pull other information from JSON and it worked there. I looked at the answers to the questions asked under this title before, but I could not get an answer to my question. How can I fix this?
