We are suddenly experiencing a problem where our logs say
The package used to work just fine and we haven't made any changes recently. Any suggestions?
Unfortunately, we do not provide error reports for failed records for Redshift. This is because, when working with Redshift, records are processed in batches and it is impossible to get a complete report.
After failed package run, please open Query Tool and run this query with your Redshift connection:
select * from 'stl_load_errors'
You will get the table with the errors as a result.
