Using a CSV file in API POST request in a cypress test

Question

I am currently trying to use a CSV file in an api POST request and I am struggling with it! So the error I am getting is a webpack error

Module parse failed: Unexpected token (1:7) You may need an appropriate loader to handle this file type, currently, no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

What do I need to add or download to accept a CSV file?

Below is the code I am using:

    const fileName = require ('file url')

    cy.fixture('fileName').then((payload) =>{
      cy.request({
        url: 'requestUrl',
        headers:  {
          method: 'POST',
          'Authorization': 'Bearer access code',
        body: payload
        }
      }).then((res) =>{
        cy.log(JSON.stringify(res))
        expect(res.status).to.eq(200)
      });
    });

  });
