Trouble with assertions when testing PDF files

Question

Objective: To find distinctive data that has been encoded in a pdf and write assertions using cypress to ensure data accuracy.

Observed Behavior: Assertions that have been written do not execute. I have tried the assertions and Cypress skipped them.

Cypress Automation Setup:

\plugins\index.js

const parsePdf = async (pdfName) => {
    const pdfPathname = path.join(repoRoot, pdfName)
    let dataBuffer = fs.readFileSync(pdfPathname)
    return pdf(dataBuffer);
};

module.exports = (on, config) => {
    on('task', {
        getPdfContent (pdfName) {
            return String(parsePdf(pdfName))
        }
    });
};

Test File admin.reports.spec.js (Uses pageObject classes)

import LoginPageObjects from "../../support/pageObjects/common.pageObjects/login.pageObjects";
import ReportsDelegateReportPageObjects
    from "../../support/pageObjects/common.pageObjects/reports.delegateReport.pageObjects";

import(LoginPageObjects);
import(ReportsDelegateReportPageObjects);

const loginPage = new LoginPageObjects();
const reportsPage = new ReportsDelegateReportPageObjects();

describe('Delegate Report Functionality', function (){

    beforeEach(() => {
        // Provides admin credentials
        loginPage.getAdminLogin();
        // Navigates to Report Menu, Selects Report, Downloads PDF report.
        reportsPage.getMenuReport();
    });

    it('should return the report and verify the data in it', function () {
        cy.readFile('C:/Users/michael.frazier/Downloads/delegate_report.pdf', 'base64').should('contain.value', "Report");
    });
});

Steps I have Tried:

I have used the .should, .expect commands, does not search the file. Used pdfparse to read the file. Lots of Google Searches

Also, I did this as well and it was ignored.

it('tests a pdf', () => {
    cy.task('getPdfContent', 'delegate_report.pdf').then(content => {
            .should('contain', "Reports" });
       })

The Ask: Is there a way where I can download the file, read the file then parse the data inside it so a assertion can be made? Can it be converted to something more easier to parse? (json, txt, etc?)

Any insight on this would be great.
