Descriptor set binding frecuency

I’m having some trouble with descriptor set binding. From what I understand, if you want to separate descriptor sets by binding frecuency you have to have different descriptor set layouts right?.

So now I have one for the camera’s descriptor set, which should be bound once, and one for each mesh’s descriptor set, which should be bound once per mesh, before calling vkCmdDrawIndexed():

layout(set = 0, binding = 0) uniform Camera {
       // ^^^ First VkDescriptorSetLayout for the camera in the VkPipelineLayout.
    mat4 view;
    mat4 projection;
} camera;

layout(set = 1, binding = 0) uniform Mesh {
       // ^^^ Second VkDescriptorSetLayout for each mesh in the VkPipelineLayout.
    mat4 model;
} mesh;

...

void main() {
    gl_Position = camera.projection * camera.view * mesh.model * vec4(inPosition, 1.0);
    outColor = inColor;
}

Now, when I bind the mesh’s descriptor set when recording the command buffers, I get this error:

Validation Error: [ VUID-vkCmdBindDescriptorSets-pDescriptorSets-00358 ] Object 0: handle = 0xfed408000000002d, type = VK_OBJECT_TYPE_DESCRIPTOR_SET; | MessageID = 0xe1b89b63 | vkCmdBindDescriptorSets(): descriptorSet #0 being bound is not compatible with overlapping descriptorSetLayout at index 0 of VkPipelineLayout 0x30f5a50000000020[] due to: Binding 0 for VkDescriptorSetLayout 0xaa989b000000001e[] from pipeline layout is type ‘VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC’ but binding 0 for VkDescriptorSetLayout 0xbb4e7a000000001f[], which is bound, is type ‘VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER’. The Vulkan spec states: Each element of pDescriptorSets must have been allocated with a VkDescriptorSetLayout that matches (is the same as, or identically defined as) the VkDescriptorSetLayout at set n in layout, where n is the sum of firstSet and the index into pDescriptorSets.

My question is, why do they overlap if they were allocated from different descriptor set layouts?
