Invalid Client

[ronykrell]

Hi, following tutorial and receiving an invalid client message. Using the format as suggested:
$ curl -u ${client_id}:${client_secret} -XPOST http://127.0.0.1:5000/oauth/token -F grant_type=password -F username=${username} -F password=valid -F scope=profile

*   Trying 127.0.0.1...

See #51, was submitting the curl command in an invalid way. Server rightfully didn't recognize a client id surrounded by ${}.

I have an issue with the example on this page:
https://github.com/authlib/example-oauth2-server

curl -u zdIKyq4ngefIcRtcU83mYK4x:oBxXfYNeqGtBq07UHrmMXLfonxTimxoJ0qpIhV9lQWYtN82Z -XPOST http://127.0.0.1:5000/oauth/token -F grant_type=password -F username=test1 -F password=valid -F scope=profile

Response: {"error": "unauthorized_client"}

There is not enough debug to let me know what the issue is. The username is test1, correct.

From http://127.0.0.1:5000/
