I attempted to test the following simple code snippet:
type Website = string;
it('loads examples', () => {
const website: Website = 'https://www.ebay.com/';
cy.visit(website);
cy.get('input[type="text"]').type('book');
cy.get('#gh-btn').click();
})
After running this code, I encountered the following error:

How can I go about solving this issue?
To prevent the uncaught:exception error in the click() method, try including the following code snippet inside your support/index.js file:
import './commands'
Cypress.on('uncaught:exception', (err, runnable) => {
// By returning false here, you can stop Cypress from failing the test
return false
})
Adding this code should help you avoid encountering the uncaught:exception issue.
To prevent Cypress from being disturbed by any uncaught exceptions within the application, it is advised to acknowledge the accepted answer. Detecting these exceptions usually indicates a bug within your app that requires fixing.
While linking to the global Cypress object, ensure that the event remains connected throughout the entire test run. However, this may not always be the most ideal scenario for your testing needs.
In cases where you specifically want to dismiss the exceptions, make sure to link the event with the cy object so that it only stays relevant for the individual test where it is utilized.
it('my test', () => {
cy.once('uncaught:exception', () => false);
// action that triggers exception
cy.get('body').click();
});
I encountered a similar issue recently Cypress Error
This error is arising from your application code, not Cypress itself.
Cannot read properties of null (reading 'textContent')
When Cypress detects uncaught errors coming from your application, it will cause the current test to fail.
You can configure this behavior by toggling off the option and listening to the uncaught:exception event. Find out more about this.
No need to panic.
Simply add this code snippet to your index.js file :)
import './commands'
Cypress.on('uncaught:exception', (err, runnable) => {
// returning false here prevents Cypress from
// failing the test
return false
})
By simply clicking on the Learn more link included in the error message, you will find all the necessary information.

According to other users:
Will this solution lead to disregarding all errors generated by the application? The accepted response implies that Cypress will overlook any uncaught exceptions.
This assertion holds true.
In my case, @DJSDev's method did not yield results while using Cypress v10.0.3.
The provided link offers a functional alternative:
it('is carrying out a crucial task', (done) => {
// this event will automatically be removed when this
// test concludes as it is linked to 'cy'
cy.on('uncaught:exception', (err, runnable) => {
expect(err.message).to.include('details about the error')
// employing mocha's async done callback to complete
// this test and demonstrate that an uncaught exception
// occurred
done()
// returning false to avoid the error from
// causing this test to fail
return false
})
// assuming this triggers an error
cy.get('button').click()
})
