Request context from getServerSideProps

The docs of tRPC context https://trpc.io/docs/v10/context

export async function createContext(opts: trpcNext.CreateNextContextOptions) {

But how to use this function from getServerSideProps (in order to use SSG helpers)?

Use the createContextInner pattern
