The following ticket has been processed in the new update v6.5.7.X:
In this update, the request URL of the CMS elements has also changed. With v6.5.7.0 it looks like this:
http://localhost:3000/index?elementId=018bed02e090700d8123e8ee0917bf89&location-id=my-element
In previous versions, however, the ?shop-id, ?shop-url, ?shopware-shop-signature, etc. were also provided as query parameters. These are of course essential in order to authenticate against the remote app server.
Therefore, our server currently sends back a Shop id is not present in request! error for every registered element in the shopping experiences.
Is this customization intentional, so that we have to adapt our app server accordingly? Unfortunately, I couldn't find any upgrade information on this.
