[Bug]: Listener call returns an error

What happened?

I was testing the template-bun on this commit : https://github.com/lenra-io/template-bun-js/commit/3e1067122107e3fdebb48e1aed3fa02b29a98048

It seems that when opening the application page, you can't click more than once on the increment button. An error occurs and if you wait a little (5 seconds), it will actually register the event properly. If you let time for the app page to initialise, this error does not occur.

Reproduce the issue with template-bun at commit 3e1067122107e3fdebb48e1aed3fa02b29a98048 and inspect the listener response. Start with packages/client_common/api/response_models/api_error.dart and packages/lenra_ui_runner/io_components/lenra_route.dart, then trace the corresponding server response. Done means repeated clicks on increment register without the null String error or delay.
