Can't Send to Upload Scanner

[xpelican]

Hello there!

I've been using Upload Scanner for years but facing this issue for the first time:

The button for "Extensions > Upload Scanner > Send to Upload Scanner" does not show up over the UI (partially - screenshot below) and ultimately, doesn't work.

Right-clicking the request doesn't print the text of the last step of the process:

And this "empty" option is still clickable, but does not do anything.

My Burp Suite version is: v2023.7.2 - Build 22197
Jython version: jython-standalone-2.7.3.jar

I've tried reinstalling the extension, and restarting Burp, no difference.

Loading the extension does not print anything in the "Errors" field, but after attempting to send stuff to the extension, these lines get printed:

I've also noticed the line that says "Deserialized 0 DownloadMatchers." I'm guessing this probably isn't normal?

On a personal note, thanks for developing this awesome tool! I've been using it for years and love it, hopefully I can solve this issue at some point.

Bumping, I'm facing the same issue.

For a working baseline it is OK for me, even though the option is blank, when clicked it populates over to the extension. Message output as follows....

Tried to send a request where no response came back via context menu to the UploadScanner. Ignoring.
