I'm running cypress on a server started in cirleci script. Though cypress can't seam to find the local server that I just started. Here's my scripts / setup. I've also tried the cypress circlci-orb and get the same error, so was trying run things myself to help debug. Here's the script details:
- run:
name: 'Run app tests'
command: |
cd app
yarn install --frozen-lockfile
yarn lint
yarn cypress:ci
package.json script:
"cypress:ci": "CYPRESS_BASE_URL=http://localhost:3000 yarn start & wait-on http-get://localhost:3000 && cypress run"
Error:

Cypress tests are kicked off and get the following error
We attempted to make an http request to this URL but the request failed without a response.
We received this error at the network level:

The solution: Up your resource class! In your circleci/config.yml
jobs:
continuous-integration:
resource_class: large
It was non obvious as there were no memory/resource warnings, but according to the circle ci team:
When the machine runs out of memory processes are killed which could include the server.
That server was the cra-server i was trying to start. I upped the resource class and voilà it ran and was found by cypress! In our case we bumped it from a medium to a large class, but may be different for you.
Here's the available resource classes you can use:
