GeoEvent Server Update Feature - what am I doing wrong?

[JonSwoveland]

Hi all, I'm new to GeoEvent Server, so please be gentle 🙂

I'm trying to set up a simple prototype GeoEvent Service that uses a "Receive JSON on a WebSocket" input connector hooked up to a "Update a Feature" output connector.

The websocket input connector (json-websocket-in) seems to be working ok.  I'm using Postman to test it and I can see the traffic in the activity graph.  The GeoEvent Definition is very simple, with two fields: UXO_STATUS (String), and OBECTID (Double).  The OBJECTID field is tagged with the TRACK_ID field.

The Update a Feature output connector is hooked up to a Feature Server, and the "Unique Feature Identifier Field" is set to OBJECTID.  

In Postman, my message to the websocket is:

[{
"OBJECTID": 1,
"UXO_STATUS": "NRM"
}]

However, when I send this, the feature with OBJECTID does not have its "UXO_STATUS" field updated.

The logs show: This output is configured to support update only. Event for 1.0 will not be inserted.

So, I'm sure something is not configured properly, but I've no idea what.

Thanks!

Take the square Brackets off your test data and try it -- 

You are telling it you are passing an array of object, not just an object - There is other processing to do if you want to handle an array of object. 

{
"OBJECTID": 1,
"UXO_STATUS": "NRM"
}

Found the problem!

I put the com.esri.ges.transport.featureService.FeatureServiceOutboundTransport log into TRACE mode, and re-sent the message from PostMan.

Here's what I saw in the logs:

Posting to URL: https://------/server/rest/services/OrdnanceByDate/FeatureServer/0/query with parameters: f=json&token=-------.&outFields=OBJECTID,OBJECTID&returnGeometry=false&where=OBJECTID IN (1.0).

OBJECTID IN (1.0)  - The GeoEvent Definition that was automatically generated from my message set the OBJECTID datatype to double.  Changing this to an integer fixed it.

I tried again with the [] brackets, and it worked as well.
