I'm trying to create a basic login command in Cypress, which was working when I used cy.visit().

After reading up on Cypress, I found out that logging in using the UI is an anti-pattern, so I'm attempting to switch over to calling cy.request() to post to the login route.

However, when I try this, I get an error that does not make sense to me:

TypeError: _locale.cy.request is not a function

This is my code in commands.js:

Cypress.Commands.add("login", () => {
  cy.request('POST', `${Cypress.config().baseUrl}/login`, {username: 'sysadmin', password: 'test'});
});

And this is where it gets called in the test:

it('Logs in successfully', () => {
  cy.login();
});

From my understanding, cy.request is a function that comes with Cypress, that can take in a method, url and body: .html#Syntax.

Can anyone please explain why Cypress isn't recognizing its own native function?

Thanks

Old question, i had the same problem, but my solution was to simply ensure that there was no import { cy } from 'date-fns/locale'; at the top of your page.
