How to add color map to image service

I have an image service created from a mosaic dataset with a pixel type of float and 32 bit depth. Evidently it isn't possible to add a color map function (I tried) to a raster that has greater than 16bit pixel depth, so I am trying to render the color map to the image service from the javascript (client side). I have tried the following script, but it's not working. I can see the image, but it shows on the map as black to white stretch.

let remapRF = new RasterFunction(); remapRF.functionName = "remap"; remapRF.functionArguments = { "InputRanges": [-0.072164394,0.040707171,0.040707171,0.118849024, 0.118849024,0.223038161, 0.223038161,0.361957011, 0.361957011,0.544288001, 0.544288001,0.752666275, 0.752666275,1.026162761], "OutputValues": [1,2,3,4,5,6,7], "Raster": "$$" } remapRF.variableName = "biovolume"; remapRF.outputPixelType = "F32"; let colorRF = new RasterFunction(); colorRF.functionName = "Colormap"; colorRF.variableName = "biovolume"; colorRF.functionArguments = { "Colormap": [[1, 11,44,122], [2, 30,144,148], [3, 14,196,65], [4, 123,237,0], [5, 247,215,7], [6, 230,142,28], [7, 194,82,60]], "Raster": remapRF };
