I have two datasets in my dataprep flow that i am trying to union. I am getting an error message that one of the dataset is broken and to fix before attempting a Union.Could someone advise what would be the best way to union two datasets? Any assistance is greatly appreciated.

Could you provide more details such as the exact error message, a data sample or a screenshot? Also, can you use that dataset in a recipe without performing the union step? – Guillem Xercavins May 03 '18 at 09:24

Sure, i am getting a message: "There is a problem with the data upstream "the_name_of_the_dataset" is broken. Please fix it before attempting to union. But i can run the two datasets separately and they look fine. – BeeKay May 04 '18 at 20:22

The union might be impacted by changes made in that dataset on a previous recipe. Docs [here](https://cloud.google.com/dataprep/docs/html/Fix-Dependency-Issues_57344608) include some steps in how to fix dependency errors. If that does not help you can provide more information or open an issue on the [PIT](https://issuetracker.google.com/issues?q=componentid:190822). – Guillem Xercavins May 07 '18 at 14:39
