Could not create `Nezasa\Checkout\Integrations\Nezasa\Dtos\Responses\Entities\ModulesResponseEntity` | Localization

[m-lotze]

Hi there,

We are getting this error on some itineraries:

Could not create `Nezasa\Checkout\Integrations\Nezasa\Dtos\Responses\Entities\ModulesResponseEntity`: the constructor requires 4 parameters, 3 given. Parameters given: startLocation, endLocation, returnConnections. Parameters missing: legs. 

I have attached the itinerary response from the api. Modules do not always have the property legs.

itinerary-response.json

Also please the check the localization of the app. There are some missing, e.g. dates are not localized and pluralization does not work in german (Nachts should be Nächte etc.)

+1 we hit this on production today (milzer/checkout v1.0.65, Laravel 12, PHP 8.3).

Stack trace identical to OP. We confirmed via our logs that real itineraries fetched from Nezasa's GET /planner/v1/itineraries/{id}?include=all legitimately omit the legs key entirely for some module entries.

Suggested fix: mark $legs and $returnConnections as nullable on the constructor and normalize to new Collection() at the call sites, or add a prepareForPipeline() hook that sets legs ??= [] before construction. Happy to open a PR if useful.

Workaround we deployed on our side: a Spatie\LaravelData\Exceptions\CannotCreateData render handler in bootstrap/app.php + a TripDetailsPage subclass that catches and renders a friendly 502.
