@abhishekkeswani

Would you please share that are you facing issue with only one document or all PDF documents which you are trying to process under this environment? Also, please share your sample source PDF document so that we can test the scenario in our environment and address it accordingly.

abhishekkeswani · July 16, 2020, 9:42am

Finance (5).zip (3.3 MB)

I have uploaded the zip file.We are unable to unzip this file

asad.ali · July 16, 2020, 6:14pm

@abhishekkeswani

There are many files in the Archive that you have shared. There is one PDF document as well.

When you say “unzip”, do you mean that you are trying to unzip the file using Aspose.PDF? Would you please explain the issue a bit more so that we can further proceed to assist you.

The code above is used to strip the JavaScript and cannot be used to unzip the file. Aspose.PDF API allows you to work with PDF documents and .zip is not the format supported by it.

abhishekkeswani · July 24, 2020, 6:32am

Here is exactly what we are trying to do,

We are trying to clean the PDF file from scripts. To do so we call the following code:

var stripper = new PdfJavaScriptStripper();
stripper.Strip(srcStream, dstStream);

where:

srcStream is our PDF file
dstStream is expected clean source file

Sometimes it works but sometimes it doesn’t work and we get an exception.

Our configuration:

Environment - Linux
Code: .net core 3.1, c#
Aspose.PDF 20.7
The source file that causes the issue is attached

Exception:

Exception: System.Exception: The root object missing or invalid

@abhishekkeswani

The document that you attached seems to be damaged/corrupted. While opening the document with Adobe Reader, we faced an error. openingerror.png (7.8 KB)

We were also unable to open it using Chrome. The invalidity of the PDF document may be the reason of the issue that you are facing. However, if you are able to open it in Adobe Reader without any error, please share it again (as it might get corrupted during the upload). We will again test it and share our feedback with you accordingly.
