Hi Adam,

The issue you are facing may be due to parsing error with one of your chars. Here is an example of what the request structure should look like. I found this thread that may be able to help you out too.

The request contains "UTF-8" encoding declaration. 

The problem might be withe the 

          <queries>żarowka</queries>

but this is also in the UTF-8.

Hi Adam,

From the resources I've seen regarding this issue, you may be running issues with how you're reading your XML file. Unfortunately, since this issue is not specifically because of our API, this issue is not within our scope.
