cloud data prep - Data Service Unknown Error when importing data from Big Query

Question

I am trying to import data from Big Query into Cloud Dataprep but I receive the following error message : "CONNEXION ERROR - Data Service unknown error" I have also this message in the console : "java.lang.NullPointerException" Any thoughts on this ?

Thanks!

I'm not entirely sure this question belongs here, it would more helpful in Stackoverflow.

This happens when there is a BQ table without a schema in the dataset.

Make sure each table in the dataset has a schema defined and you should be good to go.

You can create a table with a simple schema definition that will be updated by dataprep.
