step030 Can not load SPIR-V shader

[MHDtA-dev]

I have a function that loads spv file:

std::vector<uint32_t> loadSpv(std::string path) {
    std::ifstream file(path, std::ios::ate | std::ios::binary);

    if (!file.is_open()) {
        throw std::runtime_error("Failed to load file");
    }

    size_t fileSize = (size_t)file.tellg();
    std::vector<uint32_t> buffer(fileSize / sizeof(uint32_t));
    file.seekg(0);
    file.read((char*) buffer.data(), fileSize);
    file.close();

    return buffer;
}

I am trying to create the shader as follows:

    auto vertexCode = loadSpv("Shaders/Triangle/v.spv");

    wgpu::ShaderModuleSPIRVDescriptor vert;
    vert.chain.next = nullptr;
    vert.chain.sType = wgpu::SType::ShaderModuleSPIRVDescriptor;
    vert.code = vertexCode.data();
    vert.codeSize = vertexCode.size() * sizeof(uint32_t);

    wgpu::ShaderModuleDescriptor vertDesc;
    vertDesc.nextInChain = &vert.chain;
    vertDesc.hintCount = 0;
    vertDesc.hints = nullptr;

    wgpu::ShaderModule vertex = device.createShaderModule(vertDesc);

But it crashes with error:

thread '<unnamed>' panicked at src/lib.rs:429:5:
wgpu uncaptured error:
Validation Error

Caused by:
    In wgpuDeviceCreateShaderModule
    invalid word count

I also tried to use this variant of loading:

std::vector<char> loadSpv(std::string path) {
    std::ifstream file(path, std::ios::ate | std::ios::binary);

    if (!file.is_open()) {
        throw std::runtime_error("Failed to open file");
    }

    size_t fileSize = (size_t) file.tellg();
    std::vector<char> buffer(fileSize);

    file.seekg(0);
    file.read(buffer.data(), fileSize);

    file.close();

    return buffer;
}

    auto vertexCode = loadSpv("Shaders/Triangle/v.spv");

    wgpu::ShaderModuleSPIRVDescriptor vert;
    vert.chain.next = nullptr;
    vert.chain.sType = wgpu::SType::ShaderModuleSPIRVDescriptor;
    vert.code = reinterpret_cast<const uint32_t*>(vertexCode.data());
    vert.codeSize = vertexCode.size();
    

    wgpu::ShaderModuleDescriptor vertDesc;
    vertDesc.nextInChain = &vert.chain;
    vertDesc.hintCount = 0;
    vertDesc.hints = nullptr;

    wgpu::ShaderModule vertex = device.createShaderModule(vertDesc);

But it causes the same error.

Here is my shader code:

#version 460

layout (location = 0) in vec2 inPos;

void main() {
    gl_Position = vec4(inPos, 1, 1);
}

Compiled with glslc v.vert -o v.spv

System: MacOS Ventura (Intel)

How can I correctly load SPIR-V shader?
