Dear Jérémy,
Our app now uses React Native version 0.81.5 and Expo version 54.0.25.
When installing the dependencies with yarn, two error messages are
displayed:
error @react-native/dev-middleware at 0.81.5: The engine ‘node’ is
incompatible with this module. Expected version ‘>= 20.19.4’. Got ‘20.19.2’
and
error metro at 0.83.2: The engine ‘node’ is incompatible with this module.
Expected version ‘>=20.19.4’. Got ‘20.19.2’
npm install also displaying warnings:

I was able to trace this back to the following commits:
*
https://github.com/facebook/react-native/commit/e247be793c70a374955d798d8cbbc6eba58080ec
*
https://github.com/facebook/metro/commit/7052e5407e6ed62251767f2a5eafbe9837323bb9
As far as I understand, the React Native team has decided to support
Nodejs 20 again and arbitrarily set version 20.19.4 as the minimum version.
Kind regards,
Toni Beier
