When i do npm install i am getting following warnings, is there anything messed up with the new versions?

npm WARN @devexpress/[email protected] requires a peer of [email protected] but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of [email protected]^6.0.0 but none is installed. You must install peer dependencies yourself.

Nothing wrong with the setup, If you see the error it shows at src/main/resources/react-app/src/components/Users.js:66 There is something wrong going in your code where you are configuring dx-grid
