ArcGIS Online - Using Spatial Analysis Service From JS API

ShaunWeston — Sat, 11 Dec 2021 10:13:48 GMT

I'm trying to use one of the spatial analysis services from a javascript app I've built, but having some issues. I'd like to use this service:

https://developers.arcgis.com/en/rest/analysis/api-reference/find-hot-spots.htm

And have a ArcGIS Online developer account. I basically have some code to request a token and send it with a featureset to this service and this is the reponse I get back from the service:


inputs: {}
jobId: "j8c0cb0dbe6814e5b9ec3b29e8885da8f"
jobStatus: "esriJobFailed"
messages: [{type:esriJobMessageTypeError,�?�},�?�]
0: {type:esriJobMessageTypeError,�?�}
description: "{"messageCode": "AO_100007", "message": "FindHotSpots failed."}"
type: "esriJobMessageTypeError"
1: {type:esriJobMessageTypeError, description:Failed to execute (FindHotSpots).}
description: "Failed to execute (FindHotSpots)."
type: "esriJobMessageTypeError"

2: {type:esriJobMessageTypeError, description:Failed.}
description: "Failed."
type: "esriJobMessageTypeError"


results: {}

it's pretty vague, so I don't where it's going wrong, whether my inputs are wrong or what?

Anyone know?

Ok, so now I'm getting a different error:

ERROR 000735: analysisLayer: Value is required

Also, with this sample:

http://developers.arcgis.com/en/javascript/samples/analysis_hotspot/

I've tried with a couple of accounts (a developer account and an ArcGIS for organisations account) and it didn't work, then I tried with another account (another ArcGIS for organisations account) and it did work, so pretty confused how to use these services.

Ok managed to get this to work. It was a combination of things that was causing it to not work correctly.

I've managed to create a feature collection, load in the features to be analysed to this feature collection and send it to the service. Then I get a feature collection back and can add that to the map, so had to write a bit of code to get that to work.
