I suggest you to compare the structure of the files (yours and the sample one) and see what are the differences. Maybe your files contains some invalid characters which eventually get false parsed by NiFi. Or your files contain to many lines and so on.</P> Tue, 04 Jul 2023 06:51:32 GMT cotopaul 2023-07-04T06:51:32Z
