Cypress request by exec curl - api

Question

I am writing test cases for tutorial using https://juice-shop.herokuapp.com/#/
I am trying to add user using api.
I wanted to add a user with curl, but it fails. It responds with success but new user is missing an email that is used to log in.
I can't find my mistake
import { faker } from '#faker-js/faker';
const un = faker.internet.userName();
const domain = "#test.com";
const password = "qwerty123";
const api = "http://localhost:3000/api/Users/";
const sQuestion = "Your eldest siblings middle name?";
const sAnswer = "Joe";
describe('Login test cases suite', () => {
describe('Login test cases - basic login cases', () => {
it('New user - created by api', () => {
_apiRegisterNewUser(`${un}_api${domain}`, password);
});
it('New user - created by curl', () => {
_curlRegisterNewUser(`${un}_curl${domain}`, password);
});
});
});
export function _apiRegisterNewUser(email, password){
cy.request(
{
method: 'POST',
url: api,
body: {
"email": email,
"password": password,
"securityQuestion": {
"id": "",
"question": sQuestion,
"createdAt": `${new Date().toISOString()}`,
"updatedAt": `${new Date().toISOString()}`,
},
"securityAnswer": sAnswer
}
}
)
.then((response) => cy.log(JSON.stringify(response)));
}
export function _curlRegisterNewUser(email, password){
const com =
`curl --request POST ${api}
--header "Content-Type: application/json"
--data-raw "{\"email\":\"${email}\",\"password\":\"${password}\",\"passwordRepeat\":\"${password}\",
\"securityQuestion\":{\"id\":\"1\",\"question\":\"${sQuestion}\",\"createdAt\":\"\",\"updatedAt\":\"\",},
\"securityAnswer\":\"${sAnswer}\"}"`
cy.log(com);
cy.exec(com).then((obj) => cy.log(obj.stdout));
}
