Hello,

I am trying to update a Hosted Feature Layer View with a renderer containing a multipart color ramp. I used a color ramp example from the docs docs but could not make it work:

 

 

 

renderer_definition_multipart = {  
          "type": "classBreaksDef",
          "classificationField": field,
          "classificationMethod": "esriClassifyQuantile",
          "breakCount": 5,
          "colorRamp": {
              "type": "multipart",
              "colorRamps": [
                {
                  "type": "algorithmic",
                  "algorithm": "esriHSVAlgorithm",
                  "fromColor": [255,0,0,255],
                  "toColor": [255,255,0,255],
                  "start": 0,
                  "stop": 33.3
                  
                },
                {
                  "type": "algorithmic",
                  "algorithm": "esriHSVAlgorithm",
                  "fromColor": [0,255,255,255],
                  "toColor": [0,0,255,255],
                  "start": 33.3,
                  "stop": 100
                }
              ]
            }
        }
# Update renderer
renderer = view.layers[0].generate_renderer(renderer_definition_multipart) 
update_drawing_info = {"drawingInfo": {"renderer": renderer}}
view.layers[0].manager.update_definition(update_drawing_info)

 

 

The error message I got is shown below. Not sure what is the problem, as I am not missing "algorithm"

Any Idea what I am doing wrong?
