In the requestBody init, if I want to use a parameters string in the body field, it encodes the dictionary with a leading '?' which results in a bad request. Need an option to pass the param dictionary into body without that encoding.... I may submit one but not yet.

This function below in the response protocol gives the following compile error: 'Call can throw, but it is not marked with 'try' and the error is not handled'

   private lazy var cachedJSON: JSON = {
        return JSON(data: self.data ?? Data())
    }()

Hey @malcommac,
awesome post, and exploration of networking part. I'm trying to implement cacheable operation and faced with one issue:

1. I put my cache check and loading code right before I make a network api call
2. If cache has a valid value then it resolves current promise with this value
3. But after that when I receive an updated data neither catch nor then are called

Tried to dig inside Promise implementation in Hydra and found that the reason is that in Observer call method it falls into a default case and does nothing.

What I'm doing wrong and what do you think might be the right way?

what's the reason for that? can you just have it have it as a property of the operation?

Hi! I like this approach, however, there is a confusing moment.

Do i really need to inject one "Service" to all view controllers who needs to communicate with API if the only purpose of him is be passed to operation? And i also need to create an instances of JSONOperation inside my VC, and there is no way to injecting them, which is also doesn't feel good.

Is there a way to use that in more SOA style?
