I'm having trouble using the method 'LookupAssetByID(UInt64, Optional<Boolean>)' and getting the API return an AssetResponse.

[ulrikds]

I placed a request inside the WalletConnectManager script, in the PollForAsset method, that asks for the return of the assets. Here is the code:

private async UniTaskVoid PollForAssets()
    {
        while (true)
        {
            var status = account?.ConnectionStatus ?? SessionStatus.None;
            if (status == SessionStatus.WalletConnected)
            {
                var (err, response) = await indexer.LookupAccountByID(account.Address);

                foreach (var item in response.Account.Assets)
                {
                    Debug.Log("Asset ID");

                    Debug.Log(item.AssetId);

                    Debug.Log("Amount");
                    Debug.Log(item.Amount);
                    
                    Debug.Log(indexer.LookupAssetByID( item.AssetId, true));




                    //Space Ship NRK I
                    if (item.AssetId == 157831850)
                    {
                        Debug.Log("LOOKUPASSET METODO");
                        Debug.Log(indexer.LookupAssetByID( item.AssetId, true));

                        Debug.Log(" Asset Achado");
                        quantidadeDeAsset = (int)item.Amount;

                        if (item.Amount > 0)
                        {
                            conditionalSpawnSpaceShipConfirmationNRK1 = true;
                        }
                    }
                 

                        }
                    }
                }
            }
            await UniTask.Delay(4_000);
            await UniTask.Yield();
        }
    }

But the return is something that is neither the AssetResponse structure nor asset information.

I end up not knowing how to use the method correctly. Could someone assist me in how to use the method and receive the asset properties?

Hi @ulrikds , don't forget to await!

indexer.LookupAssetByID returns a sent web request. To get the returned response, you need to await it:

var (lookupAssetResponse, lookupAssetError) = await indexer.LookupAssetByID(item.AssetId, true);
Debug.Log(lookupAssetResponse);

I managed to, it was really my mistake. I will leave a code structure that helps to go into greater depth. Perhaps it will help someone else who is a beginner.

 private async UniTaskVoid PollForAssets()
    {
        while (true)
        {
            var status = account?.ConnectionStatus ?? SessionStatus.None;
            if (status == SessionStatus.WalletConnected)
            {
                var (err, response) = await indexer.LookupAccountByID(account.Address);

                foreach (var item in response.Account.Assets)
                {

                    var (lookupAssetError, lookupAssetResponse) = await indexer.LookupAssetByID(
                        item.AssetId,
                        true
                    );
                    Debug.Log("~~~~~~~~");


                    Debug.Log("~~~~~~~~" + lookupAssetResponse.Asset.Params.Name + "~~~~~~~~");
                    Debug.Log("~~~~~~~~" + lookupAssetResponse.Asset.Params.UnitName + "~~~~~~~~");
                    Debug.Log(lookupAssetResponse.Asset.Params.UnitNameB64);
                    Debug.Log(lookupAssetResponse.Asset.Params.MetadataHash);
                    Debug.Log(lookupAssetResponse.Asset.Params.Decimals);
                    Debug.Log(lookupAssetResponse.Asset.Params.Url);
                    Debug.Log(lookupAssetResponse.Asset.Params.UrlB64);
                    // Debug.Log(lookupAssetError);


                    Debug.Log("~~~~~~~~");

                    // var s = lookupAssetResponse.Asset.Params.MetadataHash.ToString();

                    // Debug.Log(s);

                    byte[] urlB64 = lookupAssetResponse.Asset.Params.UrlB64;
                    string hexString = BitConverter.ToString(urlB64).Replace("-", "");
                    Debug.Log(hexString);

                    byte[] unitNameB64 = lookupAssetResponse.Asset.Params.UnitNameB64;
                    string hexString2 = BitConverter.ToString(unitNameB64).Replace("-", "");
                    Debug.Log(hexString2);

       
                }
            }
            await UniTask.Delay(4_000);
            await UniTask.Yield();
        }
    }

I used the WalletConnectManager class to implement my tests, inside the PollForAssets() method.
Thanks @jasonboukheir
