vite 6.0.11, @hotwired/stimulus@^3.2.2, Ubuntu 22.04, node 20.15, symfony 6.4, PHP 8.3.8,

Description

I get "TypeError: definition.controllerConstructor is undefined" in the console when vite tries to reload the page after some JS changes.
And the JS changes will not come through as the page is not reloading.

Stack:
load vite-plugin-symfony_stimulus_helpers.js:2027
load vite-plugin-symfony_stimulus_helpers.js:2026
register vite-plugin-symfony_stimulus_helpers.js:2019

How to reproduce

Install the same versions and try to let vite reload the page by doing some javascript changes.

Possible Solution

A solution for me was to downgrade both pentatrion/vite-bundle and vite-plugin-symfony to version 6.5.3.
Only downgrading to 7.0.x was not enough. Downgrade to vite 5 also did not do the trick.
The issue started after a migration.
