passed to parser was not a valid GraphQL DocumentNode.you may need to use 'graphql-tag' or another method to convert your operation into a document

Iam new to react-native,graphql and Aws AppSync . We tried to build an react-native app using the aws appsync.When i run react-native run-android it is throwing an error saying

passed to parser was not a valid GraphQL DocumentNode.you may need to use 'graphql-tag' or another method to convert your operation into a document

Please do have a look at the

https://i.sstatic.net/hr5fA.jpg

image url to get the reference.

 import { graphql, compose } from 'react-apollo';
import gql from 'graphql-tag';

 const listMessages = graphql(gql`
    query listMessages {
      listMessages {
        id
        text
        createdAt
        sentBy {
          id
          name
        }
      }
    }`)
  const createMessage = graphql(gql`
  mutation createMessage($text: String!, $sentById: ID!) {
      createMessage(input : {
        id : $sentById
        text : $text
        createdAt : "1/06/2018"
        updateAt:"1/06/2018"
      }){
       sentBy {
         id
         name
      }
      }
     }`)


     export default compose(
        graphql(createMessage,{
          options: {
            fetchPolicy: 'cache-and-network'
          }
        }, {name : 'createMessageMutation'}),
        graphql(listMessages, {
          options : {
            fetchPolicy: 'cache-and-network'
          }
        }, {name: 'listMessagesQuery'})
      )(Chat)

The above code is the basic implementation of graphql.

I can't really trace out the error Please Help me.Thanks! in advance

You can use only GQL to define your queries.

You can use either.

No need to add graphql.

import gql from 'graphql-tag';

const listMessages = gql
    query listMessages {
      listMessages {
        id
        text
        createdAt
        sentBy {
          id
          name
        }
      }
    }

You're calling the graphql function twice -- once in your definition of listMessages and createMessage and then again in your export statement. You need to change how your defining the variables you use for your queries:

const createMessage = gql`
  mutation createMessage($text: String!, $sentById: ID!) {
    createMessage(input : {
      id : $sentById
      text : $text
      createdAt : "1/06/2018"
      updateAt:"1/06/2018"
    }) {
      sentBy {
        id
        name
      }
    }
 }`
