I got the same problem previously, and then I try to create a new credential with this role:

Make sure that your google cloud console project matches the Dialog Flow project.Your dialog flow project should have a project Id that you can find in the google console project drop down.

Create your API credentials for this project and ensure that billing is enabled.
