The request is part of a collection, and I added a variable to the collection (tried an environment as well, no change) of host being https://. It runs fine with the url being fully specified in the request, but not when it’s {{host}}/. {{host} is specified w/o any https:// qualifiers, just server.domain.com.
In the console I see the expected POST followed by a GET which seems to generate the error "The requested resource does not support http method ‘GET’ ".
Thanks for the insight. But the server in question is set up for https, and if I type it in the url manually, it works. So I’m trying to figure out what in Postman’s collection runner is different and causing the problem.
