All values in the event_type column are either reserved keywords or null

Hi,

When I want try train a model for personalize recipe, I am getting this error:

`All values in the event_type column are either reserved keywords or null`

In EVENT_TYPE I have like, click, view, bookmark.
I have Item file with one metadata and user file with meta data.

Start by reviewing the Amazon Personalize notebook and its required EVENT_TYPE schema, then compare the reported like, click, and view values with the Item and user file metadata. Done means identifying the schema mismatch or missing requirement that causes training to reject the event_type column.
