I'm trying to create a new Excel file to be downloaded. Following the documentation, I believe I'm doing everything correctly however I get the error "Object reference not set to an instance of an object." when I get to the Workbook_GetBinaryData action in my flow. All other actions complete without error when stepping through in the Debugger. I'm completely stumped - any help would be appreciated.

Ps. I've read through every forum thread I could find related to this error and/or Advanced Excel and I wasn't able to find any solutions that matched the issue I am having.
