React Router problems

I’ve tried upgrading my app to the latest versions and I have had issues mainly with “prop types” with various plugins.
The latest plugin error is with react router.
Are these the most up to date versions?

   "react": "^16.13.0",
    "react-dom": "^16.13.1",
    "react-router": "^5.1.2",
    "react-router-dom": "^5.1.2",
    "prop-types": "^15.7.2"

You can use npm view, npm view some_package_name

Go to npmjs and type in the package names.

Glitch tells me the latest version of each plugin but the question really is do they work together?

You’re the developer, you tell me?

But I see no reason why the packages you have listed wouldn’t work together using the latest versions. But that doesn’t mean you can’t have code that has been broken in an update, but unless the project is really old I doubt it.

If it is causing issues and you want more help, then link to the Glitch project.
