Semantic Layer Training Content Inaccurate for Redshift

I am unable to complete the semantic layer training course as the 6 data files provided have UUIDs in them for id fields which do not load as integers into Redshift, so each of the copy statements provided fails as the create table examples have the id columns as integers.

I can change this to VARCHAR to load the data successfully but I believe this will continue to cause problems through the training if the content is written expecting id fields to be integers.

There should be a way to flag content issues on the training course but there isn’t so posting here.
