Data Management error: Error in CommData.extractDataFromSource

Hello, I have a Data Load Rule between two Oracle Planning Cloud applications. They are under the same domain. Below are the details from the Log file, including the extract script generated from the DLR filters and the error (I think). Any advice on what to check? I have already double-checked the following: Target Apps, Import Format, Period Mapping, Category Mapping, Location, and DLR Filters.

FIX (Relative("P&L",0),Relative("Balance Sheet",0),ILvl0Descendants("Entity"),ILvl0Descendants("AllDepts"),"FY24","Working","USD","Apr","AprOL",ILvl0Descendants("DataTotal"))

DATAEXPORT "File" "," "PLACE_HOLDER_DATA_FILE_NAME.txt" "#";

ENDFIX
