*** VULKAN VALIDATION ERROR MESSAGE ***
Severity : ERROR
Type     : [VALIDATION]
Objects  : [0]: <UNNAMED OBJECT>
Message  : Validation Error: [ VUID-vkCmdDraw-None-02699 ] Object 0: VK_NULL_HANDLE, type = VK_OBJECT_TYPE_DESCRIPTOR_SET; | MessageID = 0x1608dec0 | Descriptor set VkDescriptorSet 0x0[] encountered the following validation error at vkCmdDraw time: Descriptor in binding #1 index 1 is being used in draw but has never been updated via vkUpdateDescriptorSets() or a similar call. The Vulkan spec states: Descriptors in each bound descriptor set, specified via vkCmdBindDescriptorSets, must be valid as described by descriptor validity if they are statically used by a bound shader (https://www.khronos.org/registry/vulkan/specs/1.3-khr-extensions/html/vkspec.html#VUID-vkCmdDraw-None-02699)

More recent SDK provides a better validation error:
