Async Serverless Function Trouble

For some reason I’m gettinng a "TypeError: n is not a function"
I’ve narrowed it down to this line const result = faunaFetch({ query, variables }) through adding console logs before/after it. Is there anything glaringly wrong with that line, or in the faunaFetch function?

Full Function Below

const stripe = require("stripe")(process.env.STRIPE_SECRET_KEY)
const fetch = require("node-fetch")

exports.handler = async (event, context) => {
  const { user } = context.clientContext

  const faunaFetch = async ({ query, variables }) => {
    return await fetch("https://graphql.fauna.com/graphql", {
      method: "POST",
      headers: {
        Authorization: `Bearer ${process.env.FAUNA_SERVER_KEY}`,
      },
      body: JSON.stringify({
        query,
        variables,
      }),
    })
      .then(res => res.json())
      .catch(err => console.error(JSON.stringify(err, null, 2)))
  }

  const query = `
    query ($netlifyID: ID!) {
      getUserByNetlifyID(netlifyID: $netlifyID){
        stripeID
        netlifyID
      }
    }
  `
  const variables = { netlifyID: user.sub }

  const result = faunaFetch({ query, variables })

  console.log(JSON.stringify(result))
  // console.log(stripeID)

  return {
    statusCode: 200,
    body: JSON.stringify(result),
  }
}

Function is in src → functions → create-manage-link.js

Would you need to await the faunafetch call?

const result = await faunaFetch({ query, variables })

since the function is async :slight_smile:

I’ve tried that as well but still get the same error.

Have you tried returning with a callback rather than just a return?
faunaFetch({ query, variables }).then((data) => {callback(null, { statusCode: 200, body: JSON.stringify(result) })});

or something similar, bare in mind brackets might be wrong as I typed it directly here.

EDIT: I just realised that you have a 403, maybe this could be causing an issue too as you don’t have access to the POST request? Maybe the auth isnt working? (Although youd still want to pass that back to the frontend rather than log it)
