getPartnerInventoryContents() help

[jckiller]

I am trying to retrieve users inventory by fetching their inventory items using this method and trade URL.

I am getting a malformed response when attempting to fetch their inventory using this method and honestly do not know how to diagnose it, I tried a lot of things.
Error logged from inside the offer.getPartnerInventoryContents() method:

Getting similar issues with a malformed response error using the getUserInventoryContents too.

Test function

async function testFetchInventory(steamid) {

  try {

    console.log('Starting inventory fetch for steamID:', steamid);

 

    return new Promise((resolve, reject) => {

      manager.getUserInventoryContents(

        steamid,  // Steam ID of the user

        730,      // CSGO App ID

        2,        // Context ID

        true,     // Tradeable only

        (err, inventory) => {

          if (err) {

            console.error('Failed to fetch inventory:', err);

            reject(err);

            return;

          }

 

          console.log('Inventory fetch successful!');

          console.log(`Total tradeable items found: ${inventory.length}`);

         

          // Log first 3 items as a sample

          if (inventory.length > 0) {

            console.log('Sample of first 3 items:');

            inventory.slice(0, 3).forEach((item, index) => {

              console.log(`Item ${index + 1}:`, {

                name: item.market_hash_name,

                assetid: item.assetid,

                tradable: item.tradable

              });

            });

          }

 

          resolve(inventory);

        }

      );

    });

 

  } catch (error) {

    console.error('Error in testFetchInventory:', error);

    throw error;

  }

}

Thanks for the info. This is caused by CS2 inventories that have items, but which have no items that are actually visible. The returned data looks like garbage because Valve.

steamcommunity 3.48.5 fixes the error, instead returning an empty array.

As of steam-tradeoffer-manager 2.11.7, you can use the deprecated TradeOffer.loadPartnerInventory() method to get those CS2 items.
