cy.writeFile() doesn't work with new Cypress version 12.15.0

[KristinaV-Spotos]

Current behavior

With the latest Cypress version 12.15.0 cy.writeFile() is broken when trying to write response contents to pdf. It says "cy.writeFile() must only be invoked from the spec file or support file."

Started happening after this got fixed: #27099

Desired behavior

File written successfully/blank file written

Test code to reproduce

it('Download Pdf', () => {
const pdfUrl = 'http://www.pdf995.com/samples/pdf.pdf';

      cy.request({ url: pdfUrl})
          .then((response) => {
              const fileName = 'test';
              const filePath = 'downloads/' + fileName + '.pdf';
              cy.writeFile(filePath, response.body, 'binary');
  });

Hi @KristinaV-Spotos, were you able to find a workaround for this? I'm also facing the same issue with no luck
