"Could not serialize column Error" in Athena

Question

I am trying to use the crowdstrike.crowdstrike_summary.removable_media_write_hour database but am getting the following serialization error: "SERIALIZATION_ERROR: Could not serialize column 'cem_employment_start_date' of type 'timestamp(3)' at position 1:28. This query ran against the "crowdstrike_summary" database, unless qualified by the query. Please post the error message on our forum  or contact customer support  with Query Id: 1e850429-dd42-48b8-8db3-0936c8ec2775". The query I am running is the following: "SELECT * FROM "crowdstrike_summary"."removable_media_write_hour" limit 10;"

Answer

Cause: Athena engine version 3 checks to make sure that the precision of timestamps in the data is the same as the precision specified for the column data type in the table specification. Currently, this precision is always 3. If the data has a precision greater than this, queries fail with the error noted.

If you need date from the column, you can try 
SELECT DATE(my_problem_column) FROM my_table. 
Basically changing the format of timestamp to date type.
