QS101 – customers.csv import fails: customerSince not accepted as Datetime

Hi team,

In the “Merging customer data” section of QS101, importing the provided customers.csv into Data Tables fails when customerSince is set to the Datetime column type:

Validation error: value ‘17/6/2026’ does not match column type ‘date’: ‘customerSince’ expects a dateTime but we got ‘17/6/2026’.

The dates in the provided CSV use D/M/YYYY format, which the Datetime column type rejects (it expects ISO 8601, e.g. 2026-06-17).

Could the customers.csv be updated to ISO dates, or the instructions clarified on how customerSince should be configured? Right now the file doesn’t import as written.

Thanks!
