So, we've had a process that generates a document and exports it... it uses a LIST function and has worked flawlessly for years... the document contents looks like this:

Co./Last Name,Invoice #,Date,Account #,Amount,Inc-Tax Amount,Salesperson Last Name,Salesperson First Name,Tax Code,Non-GST Amount,GST Amount,Journal Memo
<<LIST('MYOBReportSundrySales','
','MYOBExport','Commas')>>

Suddenly we are getting this error below... any suggestions would be greatly appreciated:
