This was generated with VK_HEADER_VERSION 303 so you need vulkan.h and volk.h with the same header version or newer.

Alternatively, you can re-generate bindings by providing generate.py with the URL of the desired Vulkan specification XML. You can find the latest one at https://github.com/KhronosGroup/Vulkan-Docs/blob/main/xml/vk.xml
