[react-script] jsx-key Missing "key" prop for element in array when there is no array/iteration

[shrijan00003]

Describe the bug

I have upgraded the package react-scripts from "4.0.3" to "5.0.0".

I have got the "Missing "key" prop for element in array" everywhere on my codebase.

I hope this is the issue with eslint-plugin-react@7.29.0

└─┬ react-scripts@5.0.0
  └─┬ eslint-config-react-app@7.0.0
    └── eslint-plugin-react@7.29.0

Did you try recovering your dependencies?
