I'm following an Autodesk tutorial on loading CAD files in the browser with WebGL, and am trying to convert an .nwd file I've uploaded to one of their buckets to an "OBJ".
When I run the POST request in step two of the tutorial above, however, I receive a 400 (full response below) that indicates x-ads-troubleshooting: The system does not support this file format, despite the fact that of the Autodesk documentation indicates .nwd files are supported.
Here's the full path to my file (requires Oauth token): https://developer.api.autodesk.com/oss/v2/buckets/gathering-a-bulding-bucket/objects/Yale_Residential_Colleges_Arch.nwd
When I added the item to the bucket, I was given the following objectId (which the docs also refer to as the source URN):
"objectId" : "urn:adsk.objects:os.object:gathering-a-bulding-bucket/Yale_Residential_Colleges_Arch.nwd"
I base64 encoded this string and removed the excess padding (the extra == characters at the end) per the documentation, which resulted in the following:
dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6Z2F0aGVyaW5nLWEtYnVsZGluZy1idWNrZXQvWWFsZV9SZXNpZGVudGlhbF9Db2xsZWdlc19BcmNoLm53ZA
I'm now trying to convert this nwd file to an OBJ with the following command:
curl -X 'POST' -H 'Authorization: Bearer OAUTHTOKENHERE' -H 'Content-Type: application/json' -v 'https://developer.api.autodesk.com/modelderivative/v2/designdata/job' -d '{"input":{"urn":"dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6Z2F0aGVyaW5nLWEtYnVsZGluZy1idWNrZXQvWWFsZV9SZXNpZGVudGlhbF9Db2xsZWdlc19BcmNoLm53ZA"},"output":{"formats":[{"type":"obj"}]}}'
This command yields the following response:

{"diagnostic":"Failed to trigger translation for this file."}
Does anyone have any leads on what I might be overlooking? I'd be grateful for any help others can offer!
Please take a look at this list of supported translations, you'll see that translation from .nwd to .obj is not supported, only to svf (which is used for Viewer).
