@dvdksn Maybe it's how the preview works, but it looks like this is redirecting /reference/api/engine/v1.47/, but doesn't redirect /engine/api/v1.47/

• This one doesn't redirect: https://deploy-preview-21103--docsdocker.netlify.app/engine/api/v1.47/
• This one does; https://deploy-preview-21103--docsdocker.netlify.app/reference/api/engine/v1.47/

@thaJeztah ah yeah you're right! My bad!

[thaJeztah]

Something's still broken, but I don't see immediately what's the cause;

• (older API version) https://deploy-preview-21103--docsdocker.netlify.app/engine/api/v1.46/ redirects to https://deploy-preview-21103--docsdocker.netlify.app/reference/api/engine/version/v1.46/
• but for some reason https://deploy-preview-21103--docsdocker.netlify.app/engine/api/v1.47/ does not redirect, and is still a 404
• the "canonical path" works though; https://deploy-preview-21103--docsdocker.netlify.app/reference/api/engine/version/v1.47/

Is it for some reason the combination of the content/reference/api/engine/** with the /reference/api/engine/latest/ alias?

[dvdksn]

🤦🏻 I had aliased /api/engine/v1.47/ but it should be /engine/api/v1.47/, I'd swapped places of api and engine

[thaJeztah]

LOL! And there I looked at it multiple times, and didn't see it either 😂

LGTM!
