报Code=9006，获取不到最近对话列表

[ERROR] -[AVIMClient fetchConversationIfNeeded:withBlock:]blockinvoke [Line 999] Fetching conversation failed: Error Domain=AVOSCloudIMErrorDomain Code=9006 "Conversation not found." UserInfo={NSLocalizedFailureReason=Conversation not found., reason=Conversation not found.}

是什么原因？
@leeyeh 帮忙看一下

[xiaoxu]

你好，请您提供下相关的日志信息。

开启调试日志方法如下：

// 放在 SDK 初始化语句 [AVOSCloud setApplicationId:] 后面，只需要调用一次即可
[AVOSCloud setAllLogsEnabled:YES];

[xixixi]

开了然后呢？你需要什么信息，感觉开了和没开的log没啥区别

报Code=9006，获取不到最近对话列表

开启调试日志后，运行程序，复现您说的问题，粘贴下完整的 LeanCloud 日志打印信息。

麻烦了

[xiaoxu]

上面的报错是「"Conversation not found."」，查询不到会话。
根据您上面的日志，您要查询的会话的 objectId 是 5adc46ad0ad3b7276f69af55，但是在您的应用中没有此 ID 的会话，所以报错会话找不到。

[xixixi]

但是我没有单独查询某个对话的操作，只执行了findConversationsWithCallback去拉取最近的对话列表，然后报了这个error。

[xiaoxu]

在您的日志中发现： 5adc46ad0ad3b7276f69af55 这个会话是在收到 未读消息 时执行的查询操作。在后台这个会话已经被删除，所以会报错找不到会话。这个报错的逻辑是正确的。

具体流程给您详细解释一下：
在后台查询到 5adc46ad0ad3b7276f69af55 这个会话的消息是ClientID 为 1f59913a417a11e8966ba45e60cd9107 这个用户 在 4 月 22 日发送的。

在发送这个消息后，ClientID 为 74575af53fc811e8b110a45e60cd9107 的用户（也就是上面日志的当前 Client ）会收到一条未读消息。

但是在当前用户登陆之前，后台删除了此会话（Conversation 表的数据）。

当前用户去 open Client 的时候，收到服务端发来的未读消息（unread），会查询消息对应的会话。而会话却被删除了。所以报错找不到。

建议您不要轻易删除数据。按照正常的实时通信流程是不会有上述报错。

[xixixi]

明白了。有时候为了测试需要清空后台数据，导致了数据不一致。
