Compile compute shader failed

[NALLEIN]

I tried to compile a compute shader from https://developers.google.com/web/updates/2019/08/get-started-with-gpu-compute-on-the-web#compute_shader_code but failed , the result can not be used to create shader module.

#version 450

  layout(std430, set = 0, binding = 0) readonly buffer FirstMatrix {
      vec2 size;
      float numbers[];
  } firstMatrix;

  layout(std430, set = 0, binding = 1) readonly buffer SecondMatrix {
      vec2 size;
      float numbers[];
  } secondMatrix;

  layout(std430, set = 0, binding = 2) buffer ResultMatrix {
      vec2 size;
      float numbers[];
  } resultMatrix;

  void main() {
    resultMatrix.size = vec2(firstMatrix.size.x, secondMatrix.size.y);

    ivec2 resultCell = ivec2(gl_GlobalInvocationID.x, gl_GlobalInvocationID.y);
    float result = 0.0;
    for (int i = 0; i < firstMatrix.size.y; i++) {
      int a = i + resultCell.x * int(firstMatrix.size.y);
      int b = resultCell.y + i * int(secondMatrix.size.y);
      result += firstMatrix.numbers[a] * secondMatrix.numbers[b];
    }

    int index = resultCell.y + resultCell.x * int(secondMatrix.size.y);
    resultMatrix.numbers[index] = result;
  }

I think this project needs to update the glslang version.
