Can not get cypress to work in docker container

Question

I want to run cypress in docker container and for this purpose i created. For this i followed some guides and tutorials

e2e directory that has Dockerfile

FROM cypress/base:14
WORKDIR /app

# dependencies will be installed only if the package files change
COPY package.json .
COPY cypress.json .

RUN npm install
RUN npx cypress open
RUN npx cypress verify

cypress.json

  {
    "baseUrl": "http://localhost:3000",
    "reporter": "junit",
    "reporterOptions": {
      "mochaFile": "cypress/results/output.xml"
    }
  }

package.json

{
    "name": "e2e",
    "version": "1.0.0",
    "description": "Cypress tests",
    "main": "index.js",
    "scripts": {
      "test": "echo \"Error: no test specified\" && exit 1"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "private": true,
    "devDependencies": {
      "cypress": "9.5.0"
    }
}

and .npmrc

registry=http://registry.npmjs.org/
save-exact=true
progress=false
package-lock=true

modified docker-compose.yml at the root to be

version: '3.8'
services:
nextjsApp: 
    // rest    
cypress:
    image: "cypress/included:3.2.0"
    depends_on:
      - nextjs
    environment:
      - CYPRESS_baseUrl=http://nextjs:3000
    working_dir: /e2e
    command: npx cypress run
    volumes:
      - ./:/e2e
networks:
  backend:
    external: true```

Running docker-compose build does not cause or show any errors But when i run docker-compose up i get

cypress_1  | Could not find any tests to run.
cypress_1  | 
cypress_1  | We looked but did not find a cypress.json file in this folder: /e2e

How can this be solved ?
