Thats the error im encountering, it happens on every call i make to the backend via TRPC. The problem arises when i implement withAxiom in pages/api/trpc/[trpc].ts

I see that the package uses "req.headers.get", i tried to patch the headers im sending with no luck. Is this a common issue?

Here are my TRPC context without axiom: `const createInnerTRPCContext = ({ auth, req }: AuthContext) => { return { auth, prisma, req, } }

export const createTRPCContext = (opts: CreateNextContextOptions) => { return createInnerTRPCContext({ req: opts.req, auth: getAuth(opts.req), }) }`

Im trying to implement this because i linked the application with Vercel but my function logs are not showing on the Axiom dashboard

I'm running into this same issue. It not only fails to log, it causes all my trpc requests to fail.
