Currently, PipelineInference creates an EntryPoint JSON graph beginning with:

{'Nodes' : [{
  "Name": "TextAnalytics.TextTransform",
  "Inputs": {
    "Column": {
      "Name": "text_tf",
      "Source": [
        "text"
      ]
    },
    
}}]}

The initial 'Nodes' should have double-quotes like "Nodes". JSON spec requires double quotes on keys.

As is, this fails a JSON.parse(), which makes the created JSON difficult to work with in NodeJS.
