[FIXED] How can I run my React Application in Jenkins before running Cypress?

Issue

In order to Run Cypress in Jenkins, I have to run my React application first.

But when Jenkins is running the React application, it throws the following error:

Error from chokidar (/data/node_modules/@babel/runtime/regenerator): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@babel/runtime/regenerator'

Error from chokidar (/data/node_modules/@emotion/unitless/dist): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@emotion/unitless/dist' Error from chokidar (/data/node_modules/@pmmmwh/react-refresh-webpack-plugin/lib/runtime): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@pmmmwh/react-refresh-webpack-plugin/lib/runtime' Error from chokidar (/data/node_modules/@react-pdf/layout/lib/canvas): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@react-pdf/layout/lib/canvas' Error from chokidar (/data/node_modules/@react-pdf/layout/lib/page): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@react-pdf/layout/lib/page' Error from chokidar (/data/node_modules/@react-pdf/layout/lib/utils): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@react-pdf/layout/lib/utils' Error from chokidar (/data/node_modules/@react-pdf/render/lib): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@react-pdf/render/lib' Error from chokidar (/data/node_modules/@react-pdf/render/lib/utils): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@react-pdf/render/lib/utils' Error from chokidar (/data/node_modules/@react-pdf/stylesheet/lib): Error: ENOSPC: System limit for number of file watchers reached, watch '/data/node_modules/@react-pdf/stylesheet/lib'

So it has been impossible to run the App in Jenkins.

This is the Stage in the Jenkins file that throws the error:

stage('Cypress') {      
  steps {        
    configFileProvider([configFile(fileId: 'shell-aliases', variable: 'CFG_SHELL_ALIASES')]) {  
      sh '''
      source $CFG_SHELL_ALIASES > /dev/null 2>&1
      npm run start:e2e-ci          
      '''
    }    
  }
}    

And this is the script in the package.json file that it's running:

"start:e2e-ci": "REACT_APP_TEST_ENV=e2e HTTPS=true HOST=pressboxlivelocal.statsperform.com PORT=443 react-scripts start"

Solution

Try adding this env as well CHOKIDAR_USEPOLLING=1 to your start:e2e:-ci script
