Check for date greater than other date in form request

Hello,

I have tried to check if a date is greater than another date in a form.

'start_date' => 'required|date',
'end_date' => 'required|date|gt:start_date',

The problem is that even the end_date is greater than the start_date, I receive an error saying that the end_date has to be greater than the end_date.

The documentation says that gt evaluates strings, numerics, arrays and files with the size rule, but what about the evaluation of dates ?

How can I compare two dates in a form request ?

Thanks for your help.
