TypeError: Unable to modify PDF file, make sure that output file target is available and that it is not protected

Question

I'm trying to fill pdf form using HummusJS but it throws me an error TypeError: Unable to modify PDF file, make sure that output file target is available and that it is not protected while running pdf generation in AWS lambda function but its working fine on my local machine and log aren't generated. Is there any debugging option available??. I wasted 3 days for solving this issue.

Any help will highly be appreciated.

Thanks

I'm pretty sure that, There is some issue in the output file path. It's not able to store the generated pdf file. — Sagar, Mar 28 '19 at 10:49
Just from the error this looks to me as if you don't have the permission to store the generated pdf — Nishant Singh, Mar 28 '19 at 11:53

I experienced this issue when the PDF file I was reading had a size of 0. Somewhere during my tests I suspect that the PDF I was working with got overwritten with empty data and it turns out that this is what was creating the permission error.

I was working from this sample.
