Hello All, I have a data stream that ingests data then saves the new data every 10 seconds to a specific resource. This seems to work until a certain point at which all saves and gets to the resource return a 401 error until I kill the process and restart it. The server is ESS. Does anyone have an idea about this? Thanks ---

401 like this would absolutely imply your session has expired, you’d have to share some code. If you’re using `@inrupt/solid-client-authn-node`, then periodically the session will emit an event refresh token event, and then the session needs to be updated, it’s kind of documented here: [Authenticate (Node.js: Single-User App) — Inrupt JavaScript Client Libraries](https://docs.inrupt.com/developer-tools/javascript/client-libraries/tutorial/authenticate-nodejs-script/#authenticate-with-a-refresh-token) But, if your script is only updating periodically, creating a session when you do the update, rather than holding the session open may be better. ---

Thanks for the response. I see what you mean - however how do I retrieve the initial refresh token in nodejs using the Inrupt libraries? I didn’t see an example for it unless I missed it. ---

It’s emitted by an event, it is in the docs; but it all depends on what your code looks like ---

I see. I believe I am using static access as there is no mention or instance of a refresh token for authorization. After some number of saves or time, my next save is met with a 401 Unauthorized error. Is there a time/push limit for static access? ---

Even with static client credentials, you still get a time bound access token and refresh token, and sometimes an ID token, you can see this in the code here: [solid-client-authn-js/ClientCredentialsOidcHandler.ts at main · inrupt/solid-client-authn-js · GitHub](https://github.com/inrupt/solid-client-authn-js/blob/main/packages/node/src/login/oidc/oidcHandlers/ClientCredentialsOidcHandler.ts) ---

Am I correct that if one logs in with a provider whose access token is longer, one can can use that instead? For example, if, on my ESS pod, I give all rights to my [solidcommunity.net](http://solidcommunity.net) WebID and then login at [solidcommunity.net](http://solidcommunity.net), I will have a longer timeout when visiting ESS? [EDIT] … or would the longer timeout only apply to the user, but not to the app? ---

Thank you. Is there perhaps a code sample in js/ts to get the initial refresh token? I understand the onNewRefreshToken callback, but retrieving the initial refresh token was not demonstrated to my knowledge. ---

That’d depend on the identity provider of the authenticated user, and also on the pod storage provider, I think. But mostly the former.
