@jeevith thanks for the reply I have got to know the reason behind it my script takes a PDF file as input and converts checkboxes within it to yes and no and then coverts back to PDFS using some packages like tensonflow etc. May i know what can be the size to avoid pipe is broken error. BTW my script is not returning anything it just performs some actions on file and then places in specified path.
FYI here is one more query I posted related to my issue which was not resolved so I had to choose this option to convert them
How do I read a checkbox from a PDF using Document understanding framework.
