Error: smartMapping.createClassedColorRenderer: unable to find suitable style scheme.

Hi,

I don't know what wrong I'm doing here. I'm trying to implement smart mapping renderer on web app builder.

I have just copy pasted the code from sample itself still it is giving me an error.

Error: smartMapping.createClassedColorRenderer: unable to find suitable style scheme.

Can someone please help me with the issue.

I don't think that this.map.getBasemap() returns anything but undefined or null. Try manually setting the base map.

 smartMapping.createClassedColorRenderer({
   layer: layer1,
   field: "POP2007",
   basemap: "streets",
   classificationMethod: "quantile"
 }).then(function (response) {‍‍‍‍‍‍

Sure. Will try that. Thanks.
