【问题描述】：

我面临的问题是它引发了Failed to parse http response 错误。我不确定这里有什么问题？我遵循了文档，但它似乎已经过时了。

代码：

public class AniList 
    private static final String BASE_URL = "https://graphql.anilist.co";

    public void run() 
        OkHttpClient okHttpClient = new OkHttpClient.Builder().build();

        ApolloClient apolloClient = ApolloClient.builder()
            .serverUrl(BASE_URL)
            .okHttpClient(okHttpClient)
            .build();

        MediaQuery mediaQuery = MediaQuery.builder()
            .username("ojiii")
            .type(MediaType.ANIME)
            .build();

        apolloClient.query(mediaQuery).enqueue(new ApolloCall.Callback <MediaQuery.Data> () 
            @Override public void onResponse(@NotNull Response <MediaQuery.Data> dataResponse) 
                Log.d("Data", dataResponse.toString());
            

            @Override
            public void onFailure(@NotNull ApolloException t) 
                Log.e(TAG, t.getMessage(), t);
            
        );

    

GraphQL

query MediaQuery($username: String, $type: MediaType) 
    MediaListCollection(userName: $username, type: $type) 
      statusLists 
        progress
        progressVolumes
        score
        status
        notes
        repeat
        media 
          chapters
          volumes
          idMal
          episodes
          title  romaji 
        
      
    

```

【参考方案1】：

问题是我正在请求一个已弃用的、graphql 不兼容的数据结构，它仍然返回数据。

如果您遇到此问题，请确保您的 graphql 查询与 grapql 兼容。
