CSV Import fails with FormData constructor: Argument 1 does not implement interface HTMLFormElement

[djolemag]

Environment

ZoneMinder: 1.38.3
Ubuntu: 24.04.4 LTS
Browser: Firefox (i navedi verziju ako želiš)
Theme: Dark (ako je relevantno)

Steps to reproduce

Open Network Scan.
Select CSV Import.
Choose a valid CSV file.
Click Save.

Expected result

The CSV file is uploaded and monitor import starts.

Actual result

Nothing happens.

Browser Developer Console shows:

Uncaught TypeError:
FormData constructor:
Argument 1 does not implement interface HTMLFormElement

The exception points to:

skins/classic/views/js/add_monitors.js
line 145

Current code:

const form = $j('#contentForm');
var formData = new FormData(form);

It appears that form is a jQuery object instead of an HTMLFormElement.

This was discovered while testing a multi-server deployment, but the issue appears unrelated to multi-server and looks like a client-side JavaScript bug.

The console error points to the JavaScript constructing FormData from something that is no longer an actual form element. A focused browser test for CSV Import could assert that the selected CSV file is submitted and that the handler receives an HTMLFormElement, which would catch both selector drift and markup changes in the classic skin.
