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:

    

  1. inputs: {}
    2. 

  2. jobId: "j8c0cb0dbe6814e5b9ec3b29e8885da8f"
    3. 

  3. jobStatus: "esriJobFailed"
    4. 

  4. messages: [{type:esriJobMessageTypeError,�?�},�?�]
      1. 

    1. 0: {type:esriJobMessageTypeError,�?�}
        1. 

      1. description: "{"messageCode": "AO_100007", "message": "FindHotSpots failed."}"
        2. 

      2. type: "esriJobMessageTypeError"
        3. 

    2. 1: {type:esriJobMessageTypeError, description:Failed to execute (FindHotSpots).}
        1. 

      1. description: "Failed to execute (FindHotSpots)."
        2. 

      2. type: "esriJobMessageTypeError"
        3. 


      3. 2: {type:esriJobMessageTypeError, description:Failed.}
          1. 

        1. description: "Failed."
          2. 

        2. type: "esriJobMessageTypeError"
          3. 



        3. results: {}
          4.



          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.
