Internal refresh of a 3-legged token passed into the work item failed

[k065167]

I could pass into the work item my 3-legged token like this:

Dictionary<string, string> authHeader = new Dictionary<string, string> { { "Authorization", $"Bearer {token}" } };

WorkItem workItem = new WorkItem()
{
    ActivityId = activityId,
    Arguments = new Dictionary<string, IArgument>
    {
        { "params", new XrefTreeArgument { Verb=Verb.Get, Url = jsonStorageId, Headers = authHeader } },
        { "results", new XrefTreeArgument { Verb=Verb.Put, Url = zipStorageId, Headers = authHeader } },
        { "adsk3LeggedToken", new StringArgument() { Value = token }},
    },
};

The work item can then access Revit files on ACC. However, my task involves reloading a large number of Revit links inside the main Revit model. This works most of the time, but sometimes it fails while loading a link. The report shows this:

[06/10/2025 17:57:20] Starting work item 9bba884a75694cc5be13089881367581

This is really strange because it could load several links with proper authentication, and then just randomly failed to refresh the token!

You can also see from the log that the work item had been running fine for over 2 hours before getting the error, so the token refresh must have worked previously in that same work item?

I'm lost here on what can fix this, so will really appreciate any help 😅

You need to do relinquish model with issue User is not sign in to Autodesk 360
