Cypress Uncaught Assertion Error despite cy.on(‘uncaught:exception’)

Can you please remove expect(err.message).to.include('of undefined') and done() from the cypress exception block and add the below piece of code inside the test & run the test again

Cypress.on('uncaught:exception', (err, runnable) => {
    // returning false here prevents Cypress from
    // failing the test
    return false
})
