Not working after upgrade to 1.1.6 in integration testing with mocha and supertest

[Ks89]

I'm having a weird issue after upgrading from 1.1.5 to 1.1.6.
I can't share the code, because it's closed and copyrighted but I'll try to explain a little bit the situation.

I'm having this issue while running tests with mocha and supertest.

This is my env:
macOS Catalina 10.15.2
iTerm2 with zsh as terminal
nodejs 12.14.0 and npm 6.13.4
All node modules are updated to the latest versions.

If I run npm test with version 1.1.5 everything is ok, but with 1.1.6 I receive this error:

 Uncaught TypeError: Cannot read property 'length' of undefined

I defined express-fileupload in my app.js as express middleware, as alway.
Also, in my tests I'm using this code to upload files:

rest_api_with_supertest.attach('file', FILE_AS_A_BUFFER).expect(200)

I'm sure that is something related to your package, because if I force version "=1.1.5" in my package.json everything works as expected, but not with version 1.1.6.

[Ks89]

some tests fails with the error above, but others with this one:

TypeError: Cannot read property 'call' of undefined
      at processImmediate (internal/timers.js:439:21)

[Ks89]

Probably it's something related to file uploads as "Buffer".
I need to use buffer and with supertest, it seems impossible to specify a file name in this case.

I'm encountering the same error. When in debug mode on a local machine, everything works fine. When running the application as production inside a Docker container, I get this exact error message. I have been using the latest version, will try downgrading to 1.1.5 now.

Update: On 1.1.5 everything is working as expected. This definitely is a bug in the newest version.

Hi @Ks89 ,

From trace you shared it looks that you send empty file name.
Did I understand that correct?

[RomanBurunkov]

I have two ideas regarding to this issue:

1. Set name to empty string if it hasn't been set.
2. Set name to temporary file name like tmp-1-15464564546456

[Ks89]

Yes, probably it's because I didn't set the name, but the problem is that I don't know how to set the name in case of integration testing with supertest. Filename is something in the header of the request?

[r3wt]

yes, filename is embedded in opening bytes of the file, typically referred to as the file header.

[Ks89]

Do you have any suggestion about the name of this header to set it manually into supertest?

[RomanBurunkov]

PR #207 fixes this issue.
Now parseFileName function return a temporary file name if no file name specified.
