Default values not applied on incoming requests

[devzaak]

Hi, I am trying to understand how the generation is supposed to handle default values that are part of the open api spec. In my case, I have the following spec that expects request to have default values. If I send the request to server generated and implemented with this spec the validations work, but if even a single field is not present the validation passes but request then crashes as it tries to access null pointer

As I am relatively new to golang, can you help me understand how the handling of defaults is expected to work, should I expect this to be handled by generated code, some extra middleware or something else?

Thank you
