HVV departures integration fails to load config-flow

[niklasheld]

The problem

Hi,
I've encountered a possible issue with the configuration of the "HVV Departures"-integration.

Adding an entry for the integration succeeds without any issues, and the integration itself also works fine.
However, trying to open the "Configure"-dialog for an added entry results in an error message ("Config flow could not be loaded: 400: Bad request"):

I have an entry that was added a really long time ago, and for this entry the configuration flow still loads successfully, so this issue just seems to occur with entries that were recently added.

Neither the browser console, nor the Home Assistant log in debug mode show any issues, apart from the failed request. The issue was reproducible for me in a fresh installation of Home Assistant.

What version of Home Assistant Core has the issue?

core-2023.8.2
