react-pdf/pdfjs - how to migrate cy.route to cy.interception

[joaosaro]

Hi!
I'm trying to upgrade Cypress from v6v to v12/13 but i need to change from cy.route to cy.interception. So far, I'm having a issue with a pdf file fixture. It works well in the app, but not in Cypress when change to interception method.

Previous

cy.route({
	method: 'GET',
	url: '{endpoint}',
	status: 200,
	response: 'fixture:file.pdf,binary',

I tried first to change to this and it returns an error "Warning: Invalid stream: "FormatError: Bad FCHECK in flate stream: 120, 239".

cy.interception({
	method: 'GET',
	url: '{endpoint}'
  }, {
       status: 200,
       fixture: 'file.pdf'
})

I also tried this:

cy.fixture('file.pdf', "binary").then((file) => {
	return cy.intercept(
	      {
		   method: 'GET',
		   url: '{endpoint}',
	       },
		{
			body: Cypress.Blob.binaryStringToBlob(file, 'application/pdf'),
			headers: {
				'Content-Type': 'application/pdf',
		        }
                 )}
      )}

The response is similar but the data buffer is almost the double. I looked into the documentation and other sources but I'm not getting successful answers. Anyone had this issue or know a possible cause?
