  • Suspecting an error /omission in the lab exercise. Sql query for step 2.2 does not contain the column called “customerSince”. Later on when splitting the data set into train + test parts, this errors out. I was able to validate that in the original this column is missing by printing the columns of the model_train_df. And then manually added this to the query. However, it is missing at the source where we copied the query at the first place (*glue-job.py). Would you pls double check and confirm?

Hello @mkor
Thank you for pointing this out. However, the instructions are already asking the students to add this column themselves.
