Unwanted warning componentWillMount has been renamed, and is not recommended for use. #3833

Actual Behavior

I ran npm run test and the tests all passed ✅ …but the console threw up this React unsafe lifecycle warning ⚠️.
It’s complaining about componentWillMount being deprecated and suggesting migration to UNSAFE_componentWillMount or moving logic into componentDidMount. The warning points to SideEffect(NullComponent) as the culprit.
So while the tests are green, the warning is a reminder that we’ve got some legacy lifecycle methods lurking in the codebase that could cause trouble down the line.

Expected Behavior

It should pass all the Test cases without throwing any warning specially not unsafe one.
