paperless-ng api pdf as string

[toupou]

Dear all,

I´m trying to use Node-Red to get that pdf out of paperless-ng and getting following response:

Header:

If I then try to save that as a pdf or forward via mail the pdf is corrupt and not able to be opened.

Does anyone have a clue and point me in the right direction how I need to encode/decode this?

Thanks
Philipp

This is my function-node:
`filename = msg.filename.split("/");
msg.path = "/tmp";
filename = filename.pop();

msg.headers = {
"Content-Type": "multipart/form-data; boundary=------------------------d74496d66958873e"
}

msg.payload = '--------------------------d74496d66958873e\r\n'+
'Content-Disposition: form-data; name="title"\r\n'+
'Content-Type: application/json\r\n'+
'{"title": '+filename+'}\r\n'+
'true\r\n'+
'--------------------------d74496d66958873e\r\n'+
'Content-Disposition: form-data; name="correspondent"\r\n'+
'Content-Type: application/json\r\n'+
'{"correspondent": '+msg.device+'}\r\n'+
'true\r\n'+
'--------------------------d74496d66958873e\r\n'+
'Content-Disposition: form-data; name="document"; filename="'+msg.filename+'"\r\n'+
'Content-Type: application/octet-stream\r\n'+
'\r\n'+
msg.payload+'\r\n'+
'--------------------------d74496d66958873e--\r\n';

return msg;`

Please try and give feedback.
