Using the examples from jszip and docxtemplater I am trying to add multiple docx-Documents to a zip archive and I am failing. My archive only contains docx-files with 0 Bytes that are not readable.
I think I don't understand how I can add the docx-files in binary mode to the archive. I added the rather long example code that I fused from the examples mentioned above.
Can you tell me how I have to modify the output of the generate()-function or the addition of the files to the zip-archive?

After researching the comment of muellermarkus, I was consulting with the leader of the project and I opened an issue on github. There is an answer there which I copy here as a reference. The main hurdle was the addition of {base64: true} as option when the docx-file is added to the archive.
