I am in the Getting Started React + Apollo chapter: https://www.howtographql.com/react-apollo/1-getting-started/
When I enter the following query in the Prisma Playground (as the tutorial tells me to do):
mutation CreatePrismaLink {
post(
description: "Prisma gives you a powerful database toolkit 😎"
url: "https://prisma.io"
) {
id
}
}
mutation CreateApolloLink {
post(
description: "The best GraphQL client for React"
url: "https://www.apollographql.com/docs/react/"
) {
id
}
}
I get this error message that I don't understand. It seems to be something about the server
"errors": [
{
"message": "Argument id for data.postedBy.connect.id must not be null. Please use undefined instead.\n",
"locations": [

please help me find the problem?
This is old but in case somebody else hits this issue and Googles it like me:
Unfortunately the answer here didn't work for me, but the solution is something that was covered in the Node+GraphQL tutorial, which you might not be able to figure out on your own:
In order to post you have to first create a user and then be authorized as that user. The mutation to create a user is listed as an example on the page, but unfortunately the author forgot to instruct the reader to run it before trying to create a post.
mutation {
signup(name: "Sarah", email: "sarah@prisma.io", password: "graphql") {
token
user {
id
}
}
}
Copy the token that is returned
Open the "HTTP Headers" pane in the bottom left
Enter this with your token:
{
"Authorization": "Bearer TOKEN_HERE"
}
