tRPC mutateAsync 什么都不返回

Question

This is my first attempt to use tRPC. I created a mutation named "add", which receive a URL as parameter and returns a hardcoded slug

Router

export const entryRouter = router({
  add: publicProcedure
    .input(input)
    .output(output)
    .mutation(async ({ ctx, input }) => {
      const slug = "test"

      return { slug }
    }),
})

Usage

const addEntry = trpc.entry.add.useMutation()

...

const { slug } = await addEntry.mutateAsync({ url: 'https://example.com' })

console.log(JSON.stringify({ slug })

However, it only prints an empty object ( {} )

What am I doing wrong?

PS. I am using with NextJS, on the inspector, on the.network, I can see the slug value on the response JSON

Answer 1

The problem is that I was using superjson as the transformer. Removing it solved the issue
