Entitlements/cartOffersValidation: Request failed with status code 401

[Heehes]

I am running with local node and successfully logged in, but when I paid I ran into this 401 issue
I found a history problem [401 on checkout #417]
, and try it the way it says in the comments. I manually browser logged into Epic and didn't encounter the End User License Agreement. Here is my config and my legal documents

error msg:
