Creating Renderer with Multipart Color Ramp

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?
