Attempting to get token by password grant_type problem

Hello, fellow Auth0 Community Users!
Recently I wanted to use my api from Postman perspective and to achieve that I tried to obtain token by following request:

curl --request POST
–url ‘https://mydomain.auth0.com/oauth/token
–header ‘content-type: application/x-www-form-urlencoded’
–data grant_type=password
–data ‘username=###EMAIL###’
–data ‘password=###PASSWORD###’
–data ‘client_id=###CLIENT_ID###’
–data ‘client_secret=###CLIENT_SECRET###’

And the response is:
{“error”:“server_error”,“error_description”:“Authorization server not configured with default connection.”}

I have never encountered this type of error and also after searching through google, this community, Auth0 Docs I found nothing helpful. Any ideas where I made mistake?

Thank you from advance!
Regards,
Max

Hi @maksymilian.adamowic,

Welcome to the Auth0 Community!

The Resource Owner Password Flow relies on a connection that is capable of authenticating users by username and password, so you must set the default connection for the tenant.

Steps shown here.

Hope this helps!
