Did not expect an argument to be undefined Error

Hi everyone, I am currently trying to add a feature to my app that allows an automated export of data to excel using the ExcelExporter. However, when I make the final call to export a file to excel, I get the below error in my console.     Does anyone know what could be causing this?  Thanks, Jon

So as the comments state this error is most likely caused by incorrect access rules configuration.

However, in 8.17 I had this error when I had the ‘Close Page’ activity in a microflow.
Removing the close page activity fixed the issue for me. Putting this answer here for reference.


This might help someone. It was access rules in my case, because I was trying to download a FileDocument directly. As (I think) access rules can't be added to FileDocument, I needed to use an inherited entity instead.


Hi Jonathan

Please use inherited/generalized entity from FileDocument.

Please accept the Answere, it helps:)




Hi Jonathan,


I have also faced the same issue, I checked for all the access in the security and Entity access for the generalized Entity from the file document and the close page was the problem for me. I fixed and the error resolves!


For me the issue was that I hadn’t granted access to the newly created entities of my CSV exporter module to my users. Thanks for pointing me in the right direction!
