Research direction

Reproduce the upload flow through the parse entry point and the referenced script.pdfParser call, checking when the write stream finishes relative to parsing. Use the reported error and the provided file path handling to define the fix; done means an uploaded PDF is parsed without the “stream must have data” error.

Written by the indexing model from the issue text.

Description

I am uploading the pdf file first and then trying to parse it using pdf.js but I get this error " details:"Error: PDFDocument: stream must have data". on console I am getting the file and file size is also fine after uploading it.

Code I Used :
var parse = function(payload,callback){
var data = payload;
if(data.file){
var name = data.file.hapi.filename;
var ext = name.split('.');
var extension = ext[1];
if(extension == "pdf"){
var path = __dirname + "/uploads/" + name;
checkFileExist();
var file = fs.createWriteStream(path);
file.on('error', function (err) {
console.error(err)
});
data.file.pipe(file);
var fileName = data.file.hapi.filename;
console.log(fileName);
var fileAbsolutepath = __dirname + "/uploads/" + fileName ;
console.log(fileAbsolutepath);
var parser = script.pdfParser(fileAbsolutepath,function(err,resp){
if(err){
callback(err);
}
else {
callback(resp);
}
})
callback(JSON.stringify(fileName));
}
else{
console.log("Invalid fileType");
callback(JSON.stringify("Invalid FileType"));
}
}
}

var checkFileExist = function() {
var path = __dirname + '/uploads';
fs.exists(path, function(exists) {
if (exists === false) fs.mkdirSync(path);
});
};
module.exports = {
parse: parse
}
