I'm running cypress on docker using docker run command. I got the following error:

Oops...we found an error preparing this test file:

    What does your `cypress/support/commands.js` file look like? Have you installed `cypress-iframe` using npm? – agoff Nov 09 '22 at 14:27
  • I haven't installed cypress-iframe.Should i install it on the server or inside the docker container? I'm using docker run -it -v $PWD:/e2e -w /e2e cypress/included:10.11.0 run command to run cypress. – Seura Nov 10 '22 at 10:02
  • You should add it to your `package.json` file, and when building (or starting) the container, you should add a step to run `npm install`. This is commonplace setup for docker containers using node (not just ones for Cypress) – agoff Nov 10 '22 at 14:33

If you installed cypress-iframe you should simply:

In your cypress/support/commands.js file, add the following:

import 'cypress-iframe';
// or
require('cypress-iframe');
