Readers,

good evening. thanks for taking the time to read this entire post.

We have a GP service that returns rasters based on a bounding box. the raster services are downloaded from an REST URL of esri image service created from a mosaic dataset.

Since it was working well and users could download from a multiple rest service, some users requested a modification that would enable end users to send features to this GP function and download a cookie cut of the rasters based on the feature outline.

So working GP function was copied and modified to be a new GP service. One of the input params of the new service:

Parameter: InputAOIBBox[INDENT]Data Type: GPFeatureRecordSetLayer
Display Name InputAOIBBox
Description: Some Description.
Direction: esriGPParameterDirectionInput
Default Value: [/INDENT]



    • Geometry Type:

      • HasZ: false
      HasM: false
      Spatial Reference: N/A
      Fields: None

      Features: None.
    Parameter Type: esriGPParameterTypeRequired
    Category:
name of the parameter was not changed from the previous working GP function - I hope that is not the issue.


feature set is created from 2 steps:
1. when users click on a feature based REST service mapserver layer, some features are queried and features are successfully returned as follows:

aoiSelectionLayer.selectFeatures(query, esri.layers.FeatureLayer.SELECTION_NEW, function (results) {
            dojo.forEach(results, function (individualFeature) {
                
                var individualFeatureInGCS = new esri.geometry.webMercatorToGeographic(individualFeature.geometry);
                var newGraphicsInGCS = new esri.Graphic(individualFeatureInGCS, null, individualFeature.attributes, null);


                inputAttributesList4GP = individualFeature.attributes;
                inputFeatureSetParamWGS.push(newGraphicsInGCS);
            });              
        });



Many code lines later:

var fsFeatureset2BSet = new esri.tasks.FeatureSet();
fsFeatureset2BSet.features = inputFeatureSetParamWGS;
fsFeatureset2BSet.spatialReference = new esri.SpatialReference(4326);
fsFeatureset2BSet.geometryType = "esriGeometryPolygon";



gpparams = {
"InputImageServiceURL": inputimageserviceurlwithpipe, 
"InputAOIBBox": fsFeatureset2BSet
};


Old function calls to GP were retained because they were working in the previous version of the GP funciton; of course, the new GP function URL was called.

using Fiddler the input feature information was also traced:

after sending this amount of information, server returns an error:

ERROR 000735: InputAOIBBox: Value is required</Msg>


Any suggestions: i went round and round; no solutions for me till now.

Problem solved:  GP function's input parameter was modified to be 'Feature layer' instead of feature set ALTHOUGH javascript app is sending the graphics drawn as a featureset.

var fsFeatureset2BSent = new esri.tasks.FeatureSet();
fsFeatureset2BSent.features = inputFeatureSetParamWGS;
fsFeatureset2BSent.spatialReference = new esri.SpatialReference(4326);
fsFeatureset2BSent.geometryType = "esriGeometryPolygon";



Rest Service of GP function....

Parameter: InputAOIBBox
    Data Type: GPFeatureRecordSetLayer
    Display Name InputAOIBBox
    Description: some description
    Direction: esriGPParameterDirectionInput
    Default Value:
      Geometry Type: esriGeometryPolygon
      HasZ: false
      HasM: false
      Spatial Reference: 4326 (4326)

      Fields:

      • FID ( type: esriFieldTypeOID , alias: FID )

      • Id ( type: esriFieldTypeInteger , alias: Id )

      • Shape_Length ( type: esriFieldTypeDouble , alias: Shape_Length )

      • Shape_Area ( type: esriFieldTypeDouble , alias: Shape_Area )

      Features: None.

    Parameter Type: esriGPParameterTypeRequired

    Hope it helps.
