[SOLVED] Vulkan vkCreateImage: The combination of format, type, tiling, usage and flags (...) unsupported when creating depth image

I'm trying to create an offscreen renderpass, but error append before the offscreen stuff, when I create the depth image. I took the prepareOffscreen() fonction from Sascha Willems https://github.com/SaschaWillems/Vulkan/blob/master/examples/offscreen/offscreen.cpp I had to adapt it from C++ to C, and add the multiview support. The ovrVkRenderPass argument is only here to retreive compatible color and depth format.

I 've got the message from the validation layers:

Error: [Validation] Code 180358038 (...) 
vkCreateImage: The combination of format, type, tiling, usage and flags supplied in the VkImageCreateInfo struct is reported by vkGetPhysicalDeviceImageFormatProperties() as unsupported.

But I can't find my error.
