react router /access-token did not match any routes

Plain vanilla React. I implemented the React Quirckstart on the Auth0 sitee. My landing page starts to load and then spits the error in console. The "logged in with screen appears and I can’t go any further.
Thanks for any ideas

Without seeing any code or any specific log information, I am simply guessing as to what the issue might be. It seems that you app is trying to redirect to the /access-token route - this does not look right. The callback path should be /callback - please make sure you have implemented the quickstart instructions correctly. I suggest downloading the quickstart sample which should work out of the box.

Thanks @prashant for your response. What code and log information would be beneficial to post on the forum. This is my first time posting.
