如何解决使用 Neo4j 向图形数据库添加数据时出现关键错误这个错误是什么意思？

我正在遵循本指南：https://towardsdatascience.com/create-a-graph-database-in-neo4j-using-python-4172d40f89c4

并且在运行 add_authors(authors) 和 add_papers(df) 函数时收到错误消息：

    KeyError                                  Traceback (most recent call last)

During handling of the above exception,another exception occurred:

这个错误是什么意思，我该如何解决？
