BadRequestError: checks.state argument is missing - Doc example

I get a “BadRequestError: checks.state argument is missing” every time when trying to use the Auth0 documentation example for the Authorization Code Flow. I pasted the call below with the generic data for this post, but the documentation automatically populated my Application’s parameters, which I then pasted into my App. When I try to call this, I immediately get the checks.state error every time. I have seen many references to this error, usually in production, but I can’t even get a simple example to work and I haven’t seen a simple answer yet. Thanks!

response_type=code&

redirect_uri=undefined&
scope=SCOPE&
state=STATE

I redesigned my application to not require this feature.
