I am building a shoppingcart using the Magento2 Rest API and I want to create a cart for a customer and (if not logged in) for a guest.
For guest carts is it working:
Create a guestcart:
POST /V1/guest-carts returns :cartId
Get guestcart:
GET /V1/guest-carts/:cartId returns cartObject
Fine so far, but for a customer who is logged in (using a customerToken) it doesn't work:
Create a customercart (using the customertoken):
POST /V1/carts/mine returns [message] => Cannot create quote
So i tried this workaround (using API token) but it returns the same message:
Create a customercart (using the API token):
POST /V1/customers/:customerId/carts returns [message] => Cannot create quote
I get the same result for different customers.
Does anyone has a clue?
Using Magento 2.2.5
