Forming multiple arguments via "arguments:"

I would like to pass the following to a program via arguments but it errors out.

Here is my code snippet

#!/usr/bin/env cwl-runner

cwlVersion: v1.0
class: CommandLineTool
requirements:
  - class: InlineJavascriptRequirement
baseCommand: blender_ttcam
arguments:
#  - ${
#        return "--script " + inputs.blenderScript.path + "--input " + inputs.inputAlembicMesh.path + "--output " + inputs.outputAlembicCamera.path;
#    }
  - "--script"
  - ${inputs.blenderScript.path}
  - "--input"
  - ${inputs.inputAlembicMesh.path}
  - "--output"
  - ${inputs.outputAlembicCamera.path}
inputs:
  - id: blenderScript
    type: File
  - id: inputAlembicMesh
    type: File
  - id: outputAlembicCamera
    type: File
successCodes:
  - 0
outputs: []

I would like to pass the following to my baseCommand

--script `pwd`/blender_ttcam_script.py --input `pwd`/monkey.abc --output `pwd`/generated_camera.abc

I have difficult stitching all the arguments to pass to my baseCommand.

Cheers

Answering my own question, the following works for me

arguments: ["--script", $(inputs.blenderScript.path), "--input", $(inputs.inputAlembicMesh.path), "--output", $(inputs.outputAlembicCamera.path)]

To summarize: CWL Parameter References are in the form $( ), not ${ }.
