I'm not entirely sure if this is because of the tool not working well with that particular case or if there is something in documentation I missed about configuration options. But what is the expected behavior for HTTP PUT for paths that have a required path parameter in them?

Here is the error I'm receiving when trying to run these tests against my API (full URL path is redacted):
