Mistakenly using https on outbound HTTP request results in hard-to-debug error #721
Description
I sent an outbound HTTP request to https://localhost:3001/ when I meant to write http://localhost:3001/. It failed with just RequestError. There was nothing in the error or in Spin logs. In the end I had to hack a println! into the Spin source to figure out what was going on. This is a suboptimal diagnostic experience.
