CypressError: `cy.request()` failed on:

http://elastic:changeme@localhost:6151/api/solutions/security/graphql

The response we received from your web server was:

  > 400: Bad Request

This was considered a failure because the status code was not `2xx` or `3xx`.

If you do not want status codes to cause failures pass the option: `failOnStatusCode: false`
