Data Integration Tool

Hi There:
The prevailing error in a data integration is “Processing failed for data rows matching transactions_id = ‘2539419205750’transactions_order_id=’1967148171382′.”

Both transactions_id and transactions_order_id are the key fields of the integration, which has been used for about a year and began reporting this error only about two weeks ago and every day since.

Below is part of the Query in the Data Source.

Does the issue have to do with the use of varchar syntax instead of, say, char?

Thank you!  Much appreciated!
