andorid 接入 implementation 'com.coze:coze-api:0.2.8' 报错误 ！！

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class com.coze.openapi.client.connversations.message.model.MessageContentType and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.coze.openapi.client.chat.CreateChatReq["messages"]->java.util.Collections$SingletonList[0]->com.coze.openapi.client.connversations.message.model.Message["contentType"])

No serializer found for class com.coze.openapi.client.connversations.message.model.MessageContentType and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)

首先使用实现 'com.coze:coze-api:0.2.8' 复现报告的异常，然后跟踪从 CreateChatReq 经过 messages 到 MessageContentType 的序列化过程。当请求能够成功序列化且不再出现报告的 InvalidDefinitionException 时，即表示完成。
