Cannot read property 'chunk' of undefined

[danielflippance]

I'm seeing the following error when using the node-plupload sample code from the README.md along with the plupload custom sample from http://www.plupload.com/docs/Getting-Started#full-example:

Process Error: TypeError: Cannot read property 'chunk' of undefined
TypeError: Cannot read property 'chunk' of undefined
    at /blah/blah/node_modules/node-pluploader/index.js:118:16
    at /blah/blah/node_modules/node-pluploader/node_modules/multiparty/index.js:116:9
    at /blah/blah/node_modules/node-pluploader/node_modules/multiparty/index.js:108:9
    at process._tickDomainCallback (node.js:459:13)

index.js 118 is the following code:

116: form.parse(req, function(err, fields, files) {
117:
118: if (!fields.chunk) {

Any idea why fields would be undefined? I'm using ExpressJS 4.

Is err populated? I see it is passed into the function on https://github.com/faceleg/node-pluploader/blob/master/index.js#L116 but I never wrote code to check it - this is where I would start

[danielflippance]

Yep: "Error: stream ended unexpectedly". Looking into what might cause this...

Did you ever get to the bottom of this?

Hello folks. This problem was resolved for me by checking if path to save file is correct. It wasn't for me, so i've changed it and is working very well. I hope I've helped

[faceleg]

@VicSoft was that a change in your code or is there a change required in this library?

[VicSoft]

on my own code. When i instantiate the library i have to pass the string value from my directory to uploadDir key on object param from Pluploader class, something like: /var/www/mywebsitedir.com/public/files/ ... this path was with read only permissions or wrong.

[faceleg]

Right. Thanks for the reply. I suppose it would be best if pluploader reported a better error in this situation.

[VicSoft]

Yeah, you're welcome. This error isn't specifies rightly the causes. But i think that is related with the folder to save file. Good lucky

check plupload multipart option on client side.
multiparty module check content-type if is multipart/form-data.
so plupload multipart option have to set 'true'.
