~I don't get why some tests fail~

Ok, I had done something not smart, reverted that now. Should be good to go.

I have sensible and rate limit both set. Do I need to change anything to update to to v8?

I have a similar setup and upgrading to v8 required no changes. If you have routes with a custom error handler where you don't set a reply code or don't use something like reply.redirect(), you might need to set the reply code yourself. For other routes, the error response should be identical to v7.

I see, thank you!
