Save token info in DB

[baloodevil]

I am trying to persist token information to a database so that the system can connect on the user's behalf. The token includes scope for offline_access. In the callback page...

	const client = await smart(req, res).ready();
	const tokenResponse = client.getState("tokenResponse");
	// Save tokenResponse to database

Then on another page...

	// Load tokenResponse from database
	const options: fhirclient.ClientState = {
		serverUrl: "https://somefhirserver.com/fhir",
		tokenResponse,
	};
	const client = smart(req, res).client(options);

But this results in Error: Unable to refresh. No tokenUri found. First, why is it trying to refresh if the original tokenResponse was generated within the 3600 second timeframe? I can see that fhirclient checks session for SMART_KEY, then uses that name to get another object that includes tokenResponse. Maybe I need to store the entire object (the one has tokenResponse and other properties like redirectUri) and pass that as options.
