推荐答案
我完全重写了代码，而后记单词没有错误.我认为，尽管我以前无法跟踪任何重复的ID，但肯定有一个.这次也发生了相同的错误，我发现自己引入了一个重复项.如果有人遇到相同的错误，我认为很有可能是由手动插入重复ID引起的重复引起的.
I completely re-write the code and there was no error afterwords. I think that although I couldn't trace any duplicate Ids in previous time, there must have been one. This time also the same error occurred and I found that there is a duplication introduced by myself. If anyone get the same error, I think there is a very high possibility that it is caused by duplicates in manual insertion of duplicate ids.
