applyEdits addCalibrationPoints returns Unable to complete operation

[Andy_Richardson]

Hi All,

I'm getting the following error when attempting to addCalibrationPoints using the Linear Referencing Service applyEdits REST API function:
{'error': {'code': 500, 'message': 'Unable to complete operation.', 'details': []}}

• I'm executing this from an ArcGIS Pro Python script tool.
• Enterprise version is 11.3.
• ArcGIS Pro version is 3.3 (though I don't think it matters because I'm calling applyEdits from Python).

I can manually add a calibration point in Pro using the Location Referencing Add Calibration Point tool; same service, same version.

This is what the applyEdits payload looks like:

https://MyServer/server/rest/services/MyService/MapServer/exts/LRServer/applyEdits
?f=json
&token=MyToken
&gdbVersion=MY.NAME@MY.ORG.AR_250212b
&sessionId={51777728-f672-4805-9831-b1800715f796}

"networkLayerId": 3, 
"routeId": "LOC103431P",

"geometry": { "x": 441393.9140999997, "y": 3626705.8938999996}, "measure": 0.26968174 }
]
}
]

The CalibrationPoints service layer id is 1 and the Network service layer id is 3.

I don't believe geometry needs a spatialReference because the input geometry spatialReference matches the CalibrationPoints spatialReference, but I've tried it anyway with the same results.

I don't believe recalibrateRouteDownstream or retire are required either, but I've tried them anyway, with the same results.

I have successfully executed applyEdits to update Event fields (applyEdits/updates) and to retire a route (applyEdits/retireRoute) so it seems like I'm setting everything up properly. That basic workflow is:

1. Get a sessionId and versionGuid
2. startReading
3. startEditing
4. acquire a lock on the route
5. applyEdits (response is 'Unable to complete operation.')
6. release lock
7. stopEditing
8. stopReading

This workflow very closely follows a presentation at the 2021 Developer Summit for adding a calibration point:

Thanks for any help!

I resolved the problem, it was as simple as including the geometry "z" value since calibration points are PointZ geometry.

"geometry": { "x": 441393.9140999997, "y": 3626705.8938999996, "z": 0}, "measure": 0.26968174 }

@Andy_Richardson thanks for posting the solution - its the little things.
