Duplicate Request Error

[Drepic]

Hi, I'm getting a duplicate response error (EResult: 29), when I call the following code. 

  manager.getInventoryContents(730, 2, true, (err, inventory) => {
        if (err) {
            console.log(err);
        }else{
          //other code here, never reached
        }

    });

This is run multiple times, but I need to be able to run it multiple times as the inventory is changing. How do I resolve this error ? Do I need a delay between requests ?

That's just one of those Steam errors that happens. Slowing down may help, and it may not.

Thanks, I'll see what happens.
