Loco Guide: Controller Example Does Not Work

[problem]

Hi Loco Team,
Thank you for everything you are doing. Loco is exactly what I need. I'm a Rust newbie, trying to hack my way through building a simple app with a lot of help from Claude 3 Opus :)

I'm running Loco 0.3.2

Here's where I'm stuck. The code provided at the "Building a CRUD API" step is throwing several errors. Summary:

• The imports from loco_rs (error, response, request) are not resolved. Even if I explicitly import "response", it doesn't get picked up.
• The Handler trait is not implemented for some of the handler functions (list, add, get_one, update). This suggests that the signature of these functions does not match the expected signature for the Handler trait?

Any ideas on what I could be doing wrong?

[problem]

To follow up on this, it appears that the culprit is #484 -- because of this, the example code for the articles.rs controller no longer works.
