Prisma

Hi there, I'm trying to use facebook auth, and got an error ```{ "error": "Function returned invalid status code: 0. Raw body: empty.last" }``` who knows what is it ?

where did the error originate? I mean does it say where the error occurred

I am afraid not. I assume the arrow points to where the error occurs, and it seems to be with facebook api and not with graphql

facebook api works fine, error in createGraphcoolUser, but I don't know why

You have not pasted `createGraphcoolUser`'s body - is that a custom function?

Also, this looks like its graphcool and not prisma... is it?

```async function createGraphcoolUser(api: GraphQLClient, facebookUser: FacebookUser): Promise&lt;string&gt; {
    console.log(' createGraphcoolUser ', api, facebookUser)
    const mutation = `
    mutation createUser($facebookUserId: String!, $email: String, $username: String) {
      createUser(
        facebookUserId: $facebookUserId
        email: $email
        username: $username
      ) {
        id
      }
    }
  `

    const variables = {
        facebookUserId: facebookUser.id,
        email: facebookUser.email,
        username: facebookUser.email
    }

    return api.request&lt;{ createUser: User }&gt;(mutation, variables)
        .then(r =&gt; r.createUser.id)
}```

yes, I don't have prisma, actually I don't understand for what prisma use ?

error happens here

sorry, can't help you there (I don't know graphcool)

<@U8Z4LPUP3>, does the error occur if you remove the `console.log` statement from `createGraphcoolUser`?
