componentWillReceiveProps warning

I just upgraded to 4.2 and am getting a warning in the console I was not seeing before. I don’t know if it was the 4.2 upgrade. It appeared at the same time as 4.2 but I had also recently done some overhaul.

Is anyone else seeing this (which would rule it being a 4.2 issue out)? What does this mean? I’m not willingly using react for anything right now. So sort of odd it shows up at all. It fires as soon as the engine initializes, before any of my code runs. I am using latest Firefox.

*Warning: componentWillReceiveProps has been renamed, and is not recommended for use. See for details.*

** Move data fetching code or side effects to componentDidUpdate.*
** If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at:*
** Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 17.x, only the UNSAFE_ name will work. To rename all deprecated lifecycles to their new names, you can run `npx react-codemod rename-unsafe-lifecycles` in your project source folder.*

*Please update the following components: t*

Hello Babylon.js does NOT use React so it may be on your code :wink:

The tools though uses React (so are you using the Inspector maybe?)

It is inspector I believe. As the errors only occur when I compile with it.
