Check user's details before sending an offer.

[SimpleThings]

Hello. I've seen many topics about offer.getUserDetails, but i can't understand how it works. All the time i try to send offer to a user that has no mobile steam guard or wrong token for example, im getting error, thrown by getUserDetails, but i can't get the type of this error. For example:
 Error: There was an error sending your trade offer.  Please try again later. Username is not available to trade. More information will be shown to Username if they invite you to trade.

Or (wrong token):  Error: Trade Offers can only be sent to friends.  Username is not on your Steam friends list.

I want to catch that error and show the user what the problem is, like 

if(err){
 if(err.type == "not_friends") 

 console.log("Check your tradelink!");

else if(err.type == "no_mobile")

 console.log("Please use mobile steam guard auth in order to receive offers.");
}

If there is other way than the one im using, please share. 

Im currently using:

var SendToUser = manager.createOffer(row[0].userid);

SendToUser.getUserDetails(function(err, me, them) {
                if (err) {
                    console.log("getUserDetails Error:" +err);
                    return;
                }

   //...

});

err.type is not a property that exists. You should check the text of the error message to see what caused the error.

Yeah, i know err.type does not exist. It was just an example.

What do you mean by checking the text? Maybe with IndexOf?

Okay i solved it. Thank you!

God damn it, i just lost the offer of the user and i can't resend it now. What would you recommend me Mr. Kay?

Should i save the new assetids and resend the offer after some time for example with these items, or .. i don't know what to do

Im using one file with 2 bots, one for trading and one storage. But sometimes weird errors are coming by... do you think that i need to save the items in some array in my sql table? Because all  i do now is get the items by offer.id 

And by the way, the items were stuck into the trading bot, they couldnt move to the storage.

I guess i gotta think about that
