How to port project module to fragment shader

[elfjes]

For a custom layer (+shader) I'd like to have access to the project module in the fragment shader. So I've tried to port the project module to a fs-module using the following, naive, approach (using the scripting api) (code simplified, not a full working example):

function getModel(gl){
  // setup fs, vs and geometry
  // ...

  // first port the fp32 module
  const fp32 = deck.project.dependencies[0] // I couldnt find the fp32 module in `luma` so had to extract it from project dependencies instead
  const fragFp32 = {
    name: 'fragFp32',
    fs: fp32.vs
  }

  // then port the project module
  const fragProject = {
    name: 'fragProject',
    dependencies: [fragFp32],
    fs: deck.project.vs,
    getUniforms: deck.project.getUniforms
  }
  return new luma.Model(gl, {
        vs: myCustomVS,
        fs: myCustomFS,
        myCustomGeometry,
        isInstanced: true,
        modules: [fragProject],
      });
}

Without adding fragProject as a module to my Model the layer renders just fine. However, when I add it as a module, the layer doesn't render. There are no errors in the logs, which make me think that at least this compiles just fine (compiler errors do show up in the log).

I can use the fragFp32 module directly just fine. So the error seems to be in fragProject. My guess would then be somewhere with getUniforms but I'm not sure what exactly. Can someone help me with this?
