Hi guys,

I want project invoice to be posted monthly so I create a recurring batch task under Project Module/ Periodic/ Invoices/ Post invoice proposals and the system throw me error as below.

I did full CIL and restart the server, but it doesn’t help.

Also we didn’t change anything on AOT, so i really don’t know how come errors came. Any clue how to fix it?
