                      I am trying to display values from an API using apollo client, server, ReactJS and NodeJS, Below is the code to do this:

                      Client:

                      UserPosts.js:

                      import { useMutation, useQuery } from "@apollo/client";
                      import { USERPostedImages } from "./query";
                      
                      function UserPosts() {
                        const { loading, error, data } = useQuery(USERPostedImages);
                        
                       
                       
                        return (
                          <div className="App">
                            {data.userPostedImages.map((data) => (
                              <>
                                <p key={data.posterName}>
                                  {data.url}----{data.description}
                                </p>

                      When I run my client I get the below error:

                      Uncaught TypeError: Cannot read properties of undefined (reading 'userPostedImages')
                          at UserPosts (UserPosts.js:22:1)
                      

                      I am not sure what I am doing wrong, my server is working fine and am able to see data in graphql playground but nothing shows up on the client.

                      data is not available (null) yet because it is still fetching, so to handle this, use conditional rendering with loading value.

                      const { loading, error, data } = useQuery(USERPostedImages);
                      
                      if(error) {
                       return <h1> error</h1>;
                      }
                      
                      if(loading) {
                       return <h1> loading</h1>;
                      }
                      
                      ....
