Case 4 python code

UserBird Dataiker, Alpha Tester Posts: 535 Dataiker
hello I am doing case 4 and am having problems creating the partition, I copied the code as is in the page (changing the ID for the folder) and receive this error: Job failed : Error in Python process: : An error occurred during dataset write (RrKXjRp404): IllegalArgumentException: File path pattern is not defined.

the odd thing is that if I do not partition it I do not get an error, but if I do and put it in a range of dates that are in the csv files I do get errors. have you got any answer for this?

    For some reason, the "File path pattern" setting of your partitioned output dataset is not filled. You can set it in the Settings > Partitioning tab. It is a pattern which defines how files are arranged in the partitioning columns. It should generally end with "/.*"

    For example, if you have one "time" partition and one "country" partition, you might have as pattern: /%Y/%m/%d/%{country}/.*
