PDF ingesting not working in dataflows

Anonymous 

I have the same problem, but to be more specific:

- I have a dataflow and a PBI dataset with the exact same query (that gathers data from PDF's from a Sharepoint folder).

- The PBI dataset is refreshing/working like expected

- The dataflow returns the error: "Error: PipelineException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt"
- Both the Dataset as the Dataflow are in the same Premium workspace which I am the owner of.

- The dataflow uses the advanced engine for calculations

- The preview of the dataflow returns the desired result

- Editted addition #1: I have similar dataflows running that extract data from txt and xlms files, these run without issues.

- Editted addition #2: the error occurs exactly at the moment that I use the Pdf.Tables function, or alternativly the "Invoke custom function". Without these steps, it runs fine.

I checked your suggestions, but this doesn't seem to be the problem.

Please help
