`FST_ERR_REP_ALREADY_SENT` when using `res.send()`

which is returning the following error:

as far as I am aware I can't return the Buffer directly as it would be resolved to JSON so I have to use res.send. Is there a way I can make the function not attempt to send another reply when it's returning? Using @trpc/server@11.0.0-rc.730+776d07336, fastify@5.2.1, node v22.11.0

Route not found when using Fastify adapter

The client side url was missing the /trpc prefix set in the server.
