Hi,

I am trying to merge 2 pdf files test0.pdf and test1.pdf into fullpdf.pdf document but I am getting following error. I use Debian jessie. It works on MacOSX.

I just tried this on debian 8 on 1.0.2 and it works as expected. Can you provide more details?

[wlodi83]

I use Debian GNU/Linux 8 with pdftk 2.02.

NodeJS: v6.11.3

Here is my example code:

//Adding files for merge statement to pdfFiles array //Download files from S3 let pdfFiles = []; for (let pdfFile of files_to_merge) { let uniqueKey = Math.random().toString(36).substr(2, 16); await makeGetRequest(pdfFile.s3Url, uniqueKey); pdfFiles.push(${HOME_FOLDER}/${uniqueKey}.pdf); };

//Merge downloaded files into ${timestamp}_fullpdf.pdf let date = new Date(); let timestamp = date.getTime(); let outputFile = ${HOME_FOLDER}/${timestamp}_fullpdf.pdf; await PDFMerge(pdfFiles, {output: outputFile});

@wlodi83 Don't see anything 'weird' at first glance.. The external library is complaining about the files not existing. Are you sure they are being written to the same path that the pdfFiles array is getting?

Could rule this out by logging the output right after await makeGetRequest console.log(`${uniqueKey}.pdf exists?`, require('fs'.existsSync(`${HOME_FOLDER}/${uniqueKey}.pdf`))

[wlodi83]

Yes, file exists.

From the log in the first post:

Log

2017-09-27T09:54:07.241520060Z Error: Failed to open PDF file:
2017-09-27T09:54:07.241522866Z /home/exports/test1.pdf

Command pdftk '/home/exports/test0.pdf' '/home/exports/test1.pdf' cat output /home/github/reports/tmp-33gt0sQwChMCeV

PDFtk complains about test1.pdf but not test0.pdf, and test0.pdf should most likely have been parsed first..

Unfortunately since I can't reproduce this myself and the error is outside the PDFMerge library code I'm not so sure I can help.

[wlodi83]

Yes, problem was with the file. It was somehow not created. Thanks for your help.
