Using the Get File OneDrive module and specifying a file to retrieve and upload to AirParser, I was getting incomplete uploads. Latenode would receive a HTTP 201 indicating a successful upload, but AirParser never completed parsing the PDF that was uploaded. When I download the preview of the file in the Get File module, the file opens correctly and appears intact.
To test the my theory that it appears to be passing incomplete file contents to the AirParser module, I added a Create Text File OneDrive module and had it read out the file contents to a text file and I then ran them through a base64 decoder. The header of the PDF is there, but none of the file contents are included. The entirety of the contents of the base64 encoded PDF are: JVBERi0xLjcNCiX+7f7tDQoxMyAwIG9iag0KPDwNCi9UeXBlIC9QYWdlDQovUGFyZW50IDMgMCBSDQovUmVzb3VyY2VzDQo8PA0KL1hPYmplY3QgPDwgL2ltMSAxNSAwIFIgPg==
which decodes to:
