Upgrading react-scripts to version 5.0.0 requires React 18 or later, but this project currently uses React 17.0.2 (line 37). This version incompatibility will cause build failures and runtime errors. To complete this upgrade, you must also upgrade both react and react-dom to version 18, along with updating @testing-library/react to a version compatible with React 18 (version 13 or later).

[Copilot]

The current version of @testing-library/react (11.2.6) is incompatible with React 18, which is required by react-scripts 5.0.0. This package should be upgraded to version 13 or later to maintain compatibility with the React 18 upgrade that is necessary for this react-scripts update.
