`useSuspenseQuery` with Remix causes weird "Failed to parse URL from /api" errors

I'm using tRPC with Remix (no loaders, just a client app) and as soon as I converted my codebase from

useQuery

useQuery

useSuspenseQuery

useSuspenseQuery

I'm now getting

"Failed to parse URL from /api".

"Failed to parse URL from /api".

errors in my console and server. It seems as though the queries are being run on the server for some reason (where

/api

/api

cannot be parsed because

window.location

window.location

is not available).

Any ideas what's going on? Is this intended behaviour?
