title: Calling a google sheets custom function from another custom function
body: <p>I am trying the following in a Google Sheet which produces an error because although <code>function_2()</code> <strong>correctly returns an object</strong> when I test it in the editor (or when I set it to return <code>JSON.stringify</code> and call it in the spreadsheet directly which displays correct JSON), <strong>that object is somehow converted to an empty string when it should be passed to <code>function_1()</code> as a parameter</strong>:</p>
  
  <pre><code>=function_1(B2,B3,function_2(A1,A2))
  </code></pre>
  
  <p>Any ideas?</p>
