I need to do an additional request to the backend before the original request.
But I can't access the host I need for the url in "new Request(url, 'GET', headers)".
Both target.url and target.host are null, target.host is only filled in the PostFlow.
Eg the example JS File https://github.com/SAP/cloud-api-management-samples/blob/master/authentication/saml/APIProxy/FileResource/saml.js uses context.getVariable("target.url") which always null in my tests. so this will also not work.
Any idea how to solve this problem?
