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

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

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.

Comment out node_modules/ajv/lib/keyword.js at line 64-65 for a workaround solution:

if (!validateDefinition(definition))

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

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

Dirty fix:

node_modulesajv-errorsindex.js

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

Clean fix (temporary):

Modify your package.json using this:

"resolutions": {
