Unable to get TopNaviagtionBar or children

[aiimi-cclifton]

Hello, I'm trying to get someone's previous project running again that uses this library.

It's connecting through managed identity as per this sample and seemingly successful. However any attempts to get the navigation fail with "Unresolved tokens found in API call"

e.g. ([domain] and [sitename] appearing valid, but redacted)

Original Line

var clients = context.Web.Navigation.TopNavigationBar.FirstOrDefault(n => n.Title == "Clients");

Exception:

Unresolved tokens found in API call https://[domain].sharepoint.com/sites/[sitename]/_api/Web/Navigation/GetNodeById({Id})?$filter=Title+eq+%27Clients%27&$top=1

with "GetNodeById" appearing suspect

Docs example

Following the document basics fails too:

var nodes = await context.Web.Navigation.GetAsync(n => n.TopNavigationBar);
Console.WriteLine(nodes.Id); 

Exception

Property Id was not yet loaded

Experimenting

This only return one node however, so trying:

var nodes = context.Web.Navigation.TopNavigationBar;
foreach (var node in  nodes)
{
    Console.WriteLine(node.Title);
}

Exception

Unresolved tokens found in API call https://[domain].sharepoint.com/sites/[sitename]/_api/Web/Navigation/GetNodeById({Id})?$top=100

Thoughts

Nowhere really to go with this? I've tried updating to latest with no changes. Nothing in existing issues seems to help. Similar ones seem to have alternate queries provided as answers, but these follow the docs.

The only other potential clue is: when inspecting var nodes = await context.Web.Navigation.GetAsync(n => n.TopNavigationBar), Id and Key both show '((PnP.Core.Model.SharePoint.Navigation)nodes).Key' threw an exception of type 'PnP.Core.ClientException' but I'm unsure if it's a red herring and cannot see the details anyway.
