Cypress: add undefined for commands

Hi all :wave:
I’ve just started testing with Cypress and I’m looking to modify the commands in Meteor. I’m on Meteor 2.1 :partying_face: and my project is having the following TypeError:

W20210305-15:08:53.485(0)? (STDERR) TypeError: Cannot read property 'add' of undefined

My Commands file:

import Cypress from 'cypress'

Cypress.Commands.add('resetDb', () => {
  const mongoport = 3001
  cy.exec(`mongorestore --host localhost:${mongoport}  --drop --gzip --archive=./tests/testFixtures.agz`)
})

I’ve tried Importing and Requiring Cypress in various ways and I can’t figure out what’s causing it.

Any thoughts or suggestions would be much appreciated!
