cy.request doesn't allowing me to go to next UI test cases

Trying to integrate both UI & API test cases
Created two files:
1.API test --> DO Login and writing token & saving it to fixture file

2.Spec test -->Do REAL Login by using username and password and once test case pass then in next test first get the response by using cy.request using token which saved by step1. Based on response keys search the data in search bar

API Test File:
it("Login Request API",function(){

    cy.request({
        method:"POST",
        url: POST URL,
        headers:{
         "content-type" : "application/json"
        },
        body : {
         "email": USER NAME,
         "password": PASSWORD
        },
        log: true
    }).then((response) => {
         // Parse JSON the body.
         expect(response.status).to.equal(200)
         let resbody = JSON.parse(JSON.stringify(response.body));
        cy.writeFile("File Path to store response",resbody)
     })
});

Once above test is executed then it redirect to first test . Not going to further tests
