title: Apollo/Graphql mutate array
body: <p>I am trying to mutate an array in my Vue application via Apollo to my Graphql backend.
  For example the array which I try to mutate is stored in my schema as:</p>
  <pre><code>type type1 {
      property1: [BigInt]!
  }
  </code></pre>
  <p>However, when I assign and pass a string to my mutation, i.e. &quot;[1, 2, 3]&quot; something weird happens and a large integer number will be stored, i.e. &quot;5013710821996412394&quot;, instead of my list. When I just try to pass an array I am not able to send my mutation and I get the status error 400 for bad request.</p>
  <p>What kind of datatype for the array do I need to execute my mutation correctly to my backend graphql server?</p>
