Error: Network error: field "todos" not found in type: 'query_root'

Hi I was following the NextJS Fullstack tutorial https://hasura.io/learn/graphql/nextjs-fullstack-serverless/queries/2-create-query/. After logging in with Auth0 in the frontend NextJS app, I am getting an error in the console when I try to fetch todos:

Error: Network error: field "todos" not found in type: 'query_root'

The query is:

const GET_MY_TODOS = gql`
  query getMyTodos {
    todos(where: { is_public: { _eq: false} }, order_by: { created_at: desc }) {
      id
      title
      created_at
      is_completed
  }
 }`;

When I run the same query in GraphiQL, using the x-hasura-admin-secret header it works as expected. Could you kindly advise what I doing wrong? Thanks
