Apigee edge integration (okta-oidc-into-apigee)

Dear community,

As a newly Okta user I want to integrate it with Apigee. For this I have followed below Okta tutorial:

Unfortunately I am stuck at the deployment via Yeoman. when I proceed to step 6 & 7 I fill in everything and then I get a 401 error that looks like this:

Error: Get API info returned status 401
    at Request._callback

The error seems to point to:


I can login to my Okta development portal ({org}admin.okta.com) without a problem. And the same for the Apigee Edge portal.

Can anyone point me into the correct direction? Or are there any more details that you need to assist?

Kind regards
