Cannot retrieve access tocken - authentication

Question

I am experimenting with this https://forge-digital-twin.autodesk.io/# using the gitlab code. I can display it locally (without the engine or dataflow) but I can not gain an access token.
I am using the VSCode extension and I get the code 401 (Unauthorized) error if I try to create buckets etc (hence why I am trying to get an access code). However, when I request one using this:
curl -i -X POST 'https://developer.api.autodesk.com/authentication/v1/authenticate' -H 'Content-Type: application/x-www-form-urlencoded' -d 'client_id=-----' -d 'client_secret= ----' -d 'grant_type=client_credentials' -d 'scope=data:write data:read bucket:create bucket:delete'
I get this error:
Invoke-WebRequest : Cannot bind parameter 'Headers'. Cannot convert the "Content-Type:
application/x-www-form-urlencoded" value of type "System.String" to type
"System.Collections.IDictionary".
At line:1 char:90

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have no idea where I am going wrong and have tried everything I can think of.
Hope you can help, thanks :)

Answer 1

If you're seeing 401 issues when working with the Forge extension for Visual Studio Code, make sure that you have at least one "environment" configured with your Forge client ID and secret. When you activate the extension for the first time, it should ask you for the credentials automatically, but you can also add or edit the environments at any point by going to the Visual Studio Code preferences, and looking for "forge":
And then, in the Autodesk > Forge: Environments section, hit the Edit in settings.json link and edit the environments directly as JSON, creating a new object (with title, clientId, and clientSecret properties set) if needed:
Btw. VSCode provides intelli-sense support when editing the settings.json file, so you'll see exactly which properties are expected/available in each environment.

It defaults to Invoke-WebRequest.
Try to use Invoke-RestMethod like this:
$Body = #{
grant_type = "client_credentials"
client_id = ""
client_secret = ""
scope = "data:write data:read bucket:create bucket:delete"
}
$Headers = #{
'Content-Type' = 'application/x-www-form-urlencoded'
}
$response = Invoke-RestMethod -Method Post -Uri https://developer.api.autodesk.com/authentication/v1/authenticate' -Headers $Headers -Body $Body
