How to properly use the Part Studios API's Update Feature endpoint?

ats_nisov

I need to update a feature in my model programmatically.

I read https://dev-portal.onshape.com/help for instructions, tried using the 
/partstudios/d/:did/w/:wid/e/:eid/features/featureid/:fid endpoint via the API Explorer, but couldn't do it successfully. I get the following response:

{
    "moreInfoUrl": "",
    "code": 9999,
    "message": "Error in input",
    "status": 400
}

The request body is 355 lines, so it's impossible to try to get it right by trial and error. I can't make it any simpler either as the documentation says that it needs to have the same format as what the Get Feature List endpoint gives me, and the "feature" field of my request body is exactly copied from what I got from the Get Feature List endpoint, so it should be correct.

What should I do? Are there any examples available? How do I know if my request body has all the required fields? How do I know whether it has bad fields and/or bad values?

Here's my request body: https://gist.github.com/Rubinous/a33eac2eb7aac1cc980ff3c45a98fb47.

Hi, I have experimented that error too, and I think maybe is caused by a bad formed json or something wrong with the input format.

What is it that your trying to accomplish in the api? Your json looks like its trying to create some new sketch with holes in it?

I have had some success with feature updates but it was simple stuff. Mostly updating an existing parameter. I have had to first get the feature list and find the feature I want to update, then build the json to update that value. You json looks like its trying to create a new sketch.

If you just trying to create a sketch you might have better luck using Feature Script. Its not much more forgiving but its much quicker to iterate on. Start simple and then keep adding in the complexity you need.
