While uploading a CSV of employees to sage, I got an error code 3.3978.0
I have attached the error report here. I cannot find anything under that error code and the report does not give any direction to fix the issue.
Looks like a mal-formatted CSV file. Open it with notepad (not Excel) and look for anomalies around line 24. It could be something simple like empty lines with a bunch of commas.
