Bursting a PDF with owner password set and warnings ignored throws error

[sean-schaefer]

Describe the bug When attempting to burst a PDF that has an owner password set, node-pdftk throws an error with the warning from pdftk even though ignoreWarnings is set to true and pdftk returns a 0 exit code from the same command.

To Reproduce Grab this PDF to use for input in the below code: http://www.orimi.com/pdf-test.pdf Code to reproduce:

const pdftk = require('node-pdftk')
pdftk.configure({ignoreWarnings: true})
pdftk.input('/tmp/pdf-test.pdf').burst().then(() => console.log('Success')).catch((err) => console.error(err))

Output:

Promise {
  <pending>,
  domain: 
   Domain {
     domain: null,
     _events: { error: [Function: debugDomainError] },
     _eventsCount: 1,
     _maxListeners: undefined,
     members: [] } }
> WARNING: The creator of the input PDF:
   /tmp/pdf-test.pdf
   has set an owner password (which is not required to handle this PDF).
   You did not supply this password. Please respect any copyright.

Running pdftk /tmp/pdf-test.pdf burst outputs the warning but returns a 0 exit code.

Expected behavior An error shouldn't be thrown since I'm ignoring warnings.

Found a bonehead mistake that was re-assigning the _ignoreWarnings property. This hopefully takes care of the problem. Let me know if it doesn't. I published the fix to npm as v2.0.2

Thanks @jjwilly16. I upgraded to 2.0.2 and I'm still seeing the issue. You should be able to reproduce using the code example in my original comment.

I'm experiencing the same issue using version 2.1.1 of node-pdftk. Is there a solution?

pdftk.configure({ ignoreWarnings: true });

pdftk
    .input(sourcePDF)
    .fillForm(data)
    .flatten()
    .output()
    .then(() => {
      console.log('Success');
    })
    .catch(err => {
      console.log(err);
    });

Output:

WARNING: The creator of the input PDF:
forms/myPdf.pdf
has set an owner password (which is not required to handle this PDF).
You did not supply this password. Please respect any copyright.

Hopefully fixed in 2.1.2. Let me know if it's still a problem

I'm still getting a similar error when trying to parse a document. What I'm sure of is that it has a placeholder password since the document can be opened through any other means with no issues. Is there a way I can supply an empty string as a password using your wrapper library ?

Thank you for your work on the library !

@m-majetic Can you get me a sample PDF to test?
