Cannot get access token for brand new default API

Hi @michael-bamboo,

Welcome to the Auth0 Community!

I understand that you are trying to make requests to your API using the Client Credentials Flow.

First, I would like to emphasize that the error you are encountering is likely due to the content-type header in the request.

In this case, I suggest looking at this related community thread on the solution.

Please let me know if you have any questions.

Thank you.
