Checked if the file is the cause of the error, but as per checking, it is not. Multiple changes are made in the data for testing, but as per checking, it is uploaded successfully indicating the status of the uploaded file, but when the data is clean no error on it, an error is encountered in the web application, and this is only encountered when the data it to be inserted in JDA, checked if the application is connecting successfully to JDA, as per checking it does. Requested assistance with Nate, as the error is not clearly indicated but suspected that it is on the insertion of data in JDA. Will continue the checking tomorrow.
