I am purely newbie in nodejs . I am trying to export pdf to docx using PDF API available from Adobe API services. I got few code online to achieve this from nodejs (Python not suitable here). I have file in AWS S3 , need to export the file into docx. I did minor changes in code . When I try running this . It throws an exception as : "Exception encountered while executing operation-2 Error: No input was set for operation" Need some help or advice to overcome this .
