custom keyword definition is invalid: data.errors should be boolean












6















I just created new react app using command:



create-react-app mysite.com



After installation, when I tried to open it using npm start and yarn start, I got following error.



throw new Error('custom keyword definition is invalid: '  + this.errorsText(validateDefinition.errors));
^

Error: custom keyword definition is invalid: data.errors should be boolean
at Ajv.addKeyword (/Users/myAccount/Documents/Dev/Projects/ReactJS/mysite.com/node_modules/ajv/lib/keyword.js:65:13)


Thanks.

  • Not sure, but maybe dots are not allowed in project names? That would probably cause such an error...

  • Thank you @Luan, I just created a new app with no dots and no capital letters: create-react-app profilesite, but it's still giving me same error.

  • You could also try to update your global installation of create-react-app to the latest version, or at least check in which version you are. Again, just a guess.

      I thought that was something new coming with "@symfony/webpack-encore": "^0.23.0", however there's an issue with ajv lib



      Dirty fix:



      in




      node_modulesajv-errorsindex.js




      change errors: parameter at line 14 from 'full' to true



      Clean fix (temporary):



      Modify your package.json using this:



      "resolutions": {
      "ajv": "6.8.1"
      }

                              I just tried to create app using following command:



                              npx create-react-app my-app



                              and it magically worked!



                              Thanks.
