Hi,
I have created a flow in which a .doc or .docx file is uploaded, converted to PDF, after which the .doc or .docx is deleted.
I've split the two document types in two strings.
However, with the .doc side of the flow I get this error message:

I use almost the exact same data on the .docx site, yet not error there.
Any idea how I can fix this?
Thanks in advance!
