这个问题发生在一个etl创建中，这是一个数据转换的问题，使用panda。有人能帮助我吗？

df_delivered = df.loc[(df['state'] == 2) | (df['state'] == 4) | (df['state'] == 7) | (df['direction'] == 1) | (df['delivered_at'] > last_update)]
df_delivered['Delivered'] = 1
df1 = df.merge(df_delivered, left_index=True, right_index=True, how='outer', suffixes=('', '_y'))
df1.drop(df1.filter(regex='_y$').columns, axis=1, inplace=True)
df = df1

并得到了这个错误：
上述异常是以下异常的直接原因：

Traceback (most recent call last):
