form-data file is empty with node version 14.1.0 about multiparty

[dougwilson]

Hi @chwo thank you for the report. It is indeed a bug due to some streams changes in Node.js 14. I am working to get it all fixed up. You can look though expressjs/connect-multiparty#29 if you wanted to know about some of the background, but otherwise I'll use this issue as the tracker for the Node.js 14 fix in multiparty itself 👍

Hi @barisusakli indeed, I fixed both issues with the Node.js changes: max size limit broken and files empty. The first change was an issue with a dependency being broken and it looks like it will just never be fixed, so that was a bit more involved change to test. I think it is working well, but if not we'll just field any reported bugs. I'm going to land them here now, sorry for the delay.

Hi, Can someone please update when this issue would be fixed? I see that the form.on('close') fires twice since node 14. Once with empty files and then with files populated. Thank you for looking into this.

The fix is merged into master. Please feel free to test ahead of time. I try not to release and then go to sleep, so will release first thing in the morning.

@dougwilson from my testing our upload tests pass by using the latest code from multiparty with node 14.6.0 and connect-multiparty 2.2.0

👍 waiting on connect-multiparty
