There are a lot of articles about the 'invalid_grant' error but I didn't find an answer on my situation.

At first, with Postman I am able to get an access token from /token.svc and use it successfully on the discovery service (with the cduser account).

When I run the .NET webapplication (using the DD4T.Providers.DxaModelService package)I get the following error:

[DataServiceClientException: {"error":"invalid_grant"}]

My web.config has the following configuration:

<!-- Configuration of the Discovery Service -->
<add key="discovery-service-uri" value="http://<domain>/discovery.svc" />
<add key="oauth-enabled" value="true" />
<add key="oauth-client-id" value="cduser" />
<add key="oauth-client-secret" value="CDUserP@ssw0rd" />

Do you have any suggestions on how to fix this error?

Update: I had a look at Fiddler and there is no token being requested:

  • The config looks OK and this should work, however I must ask. Did you copy the keys from a pdf maybe? If yes, then try typing them in by hand. See tridion.stackexchange.com/questions/19040/…

  • Hi @AtilaSos, I retyped the appSettings (keys and values) but I still get the same error.

  • from the stack trace above: InvalidOperationException: An error occurred when trying to create a controller of type 'MijnPostNL.Controllers.PageController'. Make sure that the controller has a parameterless public constructor.

Using Fiddler I found out that the TokenService was registered on the localhost domain. That's why the webapplication (which was running on my local machine) couldn't access the TokenService on the development server.

See screenshot below:

enter image description here

I configured the TokenService with a domainname and now it works.
