How do I fix Not Logged In error?

[What Comes Around]

Good day!

I get this error from time to time:

ConfirmationChecker Error: Not Logged In
    at Request.init (D:\Node Projects\SteamMarketBot\node_modules\request\request.js:458:31)
    at Redirect.onResponse (D:\Node Projects\SteamMarketBot\node_modules\request\lib\redirect.js:149:11)
    at Request.onRequestResponse (D:\Node Projects\SteamMarketBot\node_modules\request\request.js:986:22)
    at ClientRequest.emit (events.js:315:20)
    at HTTPParser.parserOnIncomingClient [as onIncoming] (_http_client.js:641:27)
    at HTTPParser.parserOnHeadersComplete (_http_common.js:126:17)
    at HTTPParser.execute (<anonymous>)
    at TLSSocket.socketOnData (_http_client.js:509:22)
    at TLSSocket.emit (events.js:315:20)
    at addChunk (internal/streams/readable.js:309:12)

What is strange is that the client is still connected in most cases. It still returns inventories, it still changes gamesPlayed but when accepting all confirmations, it gives me this error. So I am curious what I can do to fix the error.

Client connections and web sessions are two separate things. When steam-user connects to the Steam servers, it also negotiates a web session (which is what the cookies you've received contain). That web session expires pretty much whenever it wants, and when it does you'll get that error.

You should use the sessionExpired event in steamcommunity to detect when your web session has expired and use webLogOn() in steam-user to get a new session. Or, just call webLogOn() every half hour or so. That tends to work well enough in my experience.

Thanks! This is the solution I was looking for!
