How to use the API to execute a FeatureScript to create a custom feature?

he_qiu143

I created a Part Studio and a Feature Studio in the same document.

Here is the content of the Feature Studio.

FeatureScript 2581;
import(path : "onshape/std/common.fs", version : "2581.0");

annotation { "Feature Type Name" : "Fillet Everything" }
export const filletEverything = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {

    }
    {
        opPlane(context, id + "plane1", {
                "plane" : plane(vector(0, 0, 6) * inch, vector(0, 0, 1))
        });
    });

As you can see, this script simply creates a plane. Now, I need to use the Onshape Python API to call this FeatureScript in the Part Studio to create a plane. My Python code is as follows:

        body = {

            "btType": "BTFeatureDefinitionCall-1406",

            "features": [

                {

                    "featureType": "filletEverything",

                    "btType": "BTMFeature-134",

                    "name": "Fillet Everything 1",

                    "parameters": [],

                    "featureId": "FGMsohIYH03BN1f_0",

                    "subFeatures": [],

                    "namespace": "e03fd799aee4796bff7177d98::m4c232d7c5b8456deef0ccc33",

                    "nodeId": "QtTe+DBU77uVY1dM",

                    "returnAfterSubfeatures": False,

                    "suppressed": False

                }

            ],

        }


        res = self._api.request('post', '/api/v10/partstudios/d/' + did + '/w/' + wid + '/e/' + eid + '/features',

                                body=body)

The content of the body is obtained by calling the getFeatures API, so the body content should be correct. However, whether I use the Python API or the API Explorer, I am unable to create the plane in the Part Studio. The error message returned is as follows（from python）:

'{

  "message" : "An internal error has occurred; support code 6a3cbb3b760a3d749babc43e",

  "status" : 500,

  "code" : 0,

  "supportCode" : "6a3cbb3b760a3d749babc43e",

  "moreInfoUrl" : ""

}'

Besides that, I have also tried using other versions of the API, such as v9, as well as the default API, but none of them were able to create the plane successfully. I believe the issue lies with the FeatureScript, because I can correctly create features like sketches and extrudes using a similar approach.

The reason for using the API to execute the FeatureScript is that, through FeatureScript, I can create a sketch plane by directly specifying the point coordinates and the normal (using the newSketchOnPlane function). Since my data only contains the Origin, normal, and x information, I have no choice but to use this approach to create the sketch plane

If anyone has experience with executing FeatureScript scripts in a Part Studio via the API, or if you have any insights into what might be causing this issue, I’d really appreciate your help!
