Run Geoprocessing argument required

Hi

I have a workflow that has user select a featureset is parsed into a gptask.

However unsure of expression for argument in the Run Geoprocessing activity.

Featureset: $getFeatureGeometries1.geometries

gptask input parameter: in_features

Also, would the spatial reference (either Out or Process) need to be specified for the activity to work? 

Thanks for any help, Vincent

  The Run Geoprocessing activity takes an argument of type Object:

  

  So you can wrap your featureset in a dictionary:

  ={'in_features': $getFeatureGeometries1.geometries}

  Then you can parse out the key-value pair in_features in your GP task.

  The spatial reference argument is not required and will take the default of the input geometries:

  Great thanks Alex. For the noob such as myself could you suggest a site as a starting point on how to generate expressions such as this, trying to work out what is needed is confusing and not sure what they are ( .net /java etc or a combination / or none of the above?) thanks again for your time

  Does this GW5 - Run Geoprocessing (asynchronous) sample help you?

  That is a good example with a relatively complex argument!

  The ArcGIS REST API documentation has helped me a lot to understand what is expected of Esri data types with the Javascript SDK https://developers.arcgis.com/javascript/latest/api-reference/ working with feature services https://developers.arcgis.com/rest/services-reference/enterprise/feature-service.htm

  I'm not very good at Javascript and it has been a lot of trial-and-error for me to understand the VertiGIS REST API and what it expects, but I have learned stuff and developed "muscle memory" over time.

  Hi

  Still getting an error (from browser devtools) when running workflow:

  Invalid value for parameter Input Features - Details : Unable to parse JSON value of the parameter.

  Referring to Alex comments above:

  So you can wrap your featureset in a dictionary:

  ={'in_features': $getFeatureGeometries1.geometries} - have done this in Run Geoprocessing activity

  Then you can parse out the key-value pair in_features in your GP task.  -unsure how to do this, see image for my gptask

  Thanks, Vincent
