stashedFile stopped working when triggering another build

[yairogen]

Jenkins and plugins versions report

Jenkins: 2.516.1

I have an upload job and downstream. downstream job expects top get 2 parameters as stashed files.

example of parameter section in downstream job:

parameters {
        stashedFile 'old_file'
        stashedFile 'new_file'
}

A trigger job like this used to work fine::

                                parameters: [
                                    stashedFile(name: 'old_file', file: "output/old_files.zip"),
                                    stashedFile(name: 'new_file', file: "output/new_files.zip")
                                ],
                                wait: true

But lately it fails on error:

I tried tricks like using org.apache.commons.fileupload.disk.DiskFileItemFactory but that causes other errors since it seems like jenkins core moved to use apache commons 2 and package org.apache.commons.fileupload2.core. Seems like the plugin isn't fully compatible.

Note: This also manifests itself if I try to generate the build step using pipeline-syntax. In the gui you can see error:

We also have this error

Did that ever work?
I tried the snippet from above with a 2 year old version of this plugin and it didn't work.

[yairogen]

Yup. It worked fine in an older version. Existing pipeline just broke once we upgraded to a new server with latest version.

Do you still know what version of Jenkins and plugin you used before?

[yairogen]

I need to check if that server is still around (might take a few days), but isn't this something fixable regardless?

As mentioned I'm surprised this should have ever worked. There was just never a constructor that takes a String as the file location. And with just a string the parameter would not be able get the file as the code runs on the controller but the actual build might be running on an agent.
The only way I could see how to pass a file to a stashedFile parameter is with the approach mentioned in #126 (comment) , though I think that also doesn't work anymore right now since the shift to fileupload2

[yairogen]

For sure the move to file upload 2 is whet broke it. In my case both jobs used to run in Jenkins master node for what it's worth
