TRPCClientError: fetch failed

I get the below error when createTRPCProxyClient runs on BE of a Next.JS app hosted on Vercel:

I've been struggling for a while, and have no clue what's going on. Anybody experienced something similar? It seems to be coming from undici polyfilling fetch for node, but that's as far as I can go before the guessing game begins. This is not happening locally
