My client React app uses the following scope: openid profile email.
I’ve got two environments on Auth0 set up in exactly the same way using Universal Login. When I am signing up using development account, I am being redirected to the screen where I need to approve scope for the app. Doing the same thing on production does not result in directing me to that screen. As a result, I am getting: Grant type 'client_credentials' not allowed for the client. error and infinite redirect.
I’ve tried to delete the user account, checked environment variables, checked permissions and cleared all the cookies and nothing.
I took a look at that application in your tenants and noticed that the Client Credentials Grant Type is not selected. You can enable the client Credentials Grant Type by going to the application’s setting Tab, scrolling to the bottom of the page, toggling Advanced Settings, choosing the Grant Types tab, and checking the box for the Client Credentials Grant Type. Make sure to Save the Changes.
After making that change, you can retry and see if everything works as expected.
If this doesn’t work, could you please confirm which application you’re trying to access and provide the relevant logs?
