此问题可能是由于未授权或未设置正确的频道类型而导致的。要解决此问题，请确保您的应用程序已授权使用该频道类型，并在创建频道时提供正确的参数。以下是创建对话类型频道的示例代码：

AmityChannelNotificationConfig notificationConfig = new AmityChannelNotificationConfig.Builder()
        .setNotifyAllMembers(true)
        .setNotifyNewMessage(true)
        .setNotifyMessageEdited(true)
        .setNotifyMessageDeleted(true)
        .build();

AmityChannelOptions options = new AmityChannelOptions.Builder()
        .setVisibility(AmityChannel.ChannelVisibility.PROTECTED)
        .setChannelType(ChatChannel.TYPE_CHAT)
        .setNotificationConfig(notificationConfig)
        .build();

AmityChatClient.newChannel("channelId", options)
        .setDisplayName("Channel Name")
        .setMetaData("key1", "value1")
        .create(new ResultListener() {
            @Override
            public void onSuccess(AmityChannel channel) {
                // Channel created successfully
            }

            @Override
            public void onError(Throwable error) {
                // Handle error
            }
        });
