getInventoryHistory() returning "Error: Malformed page: no trade found"

[t3sted]

I just started using this module and I'm having trouble getting Steam inventory history. The following code always returns "Error: Malformed page: no trade found":

        // set options for the inventory history request
        const options = {
            direction: 'past', // retrieve trades that occurred further in the past than startTime
            resolveVanityURLs: true, // resolve custom profile URLs to Steam IDs
        };
        
        // make the API request to retrieve the inventory history data
        community.getInventoryHistory(options, (err, history) => {
            if (err) {
            console.error(err);
            process.exit();
            }
        
            // print the inventory history to the console
            console.log(`Inventory history (${history.trades.length} trades):`);
            for (const trade of history.trades) {
                console.log(`- ${trade.date.toISOString()}: Traded with ${trade.partnerName}`);
                console.log(`  Received: ${trade.itemsReceived.map(item => item.name).join(', ')}`);
                console.log(`  Given: ${trade.itemsGiven.map(item => item.name).join(', ')}`);
            }
            process.exit();
        });

Does anyone know why this might be happening? TYIA

getInventoryHistory is deprecated and I'd be surprised if it still works. You should use IEconService/GetTradeHistory instead.

Thanks for your reply. Everyone who's written Steam APIs seems to conflate trade history and inventory history. I'm really after complete inventory history; unfortunately, trade history doesn't account for market transactions. I suppose some combination of the two might be my only option.

getInventoryHistory was written years ago, before the inventory history page showed more than just trades. I'm not aware of anything that scrapes the newer full inventory history page.
