title: Error when calling biosphere flows an activity in ecoinvent v.3.5
body: <p>I happen to face an error when I try to call the biosphere flows of activity. And When I call the technosphere for different activities, it works fine.</p>
  
  <p>However, for the biosphere:</p>
  
  <pre><code>[in] clinker_bio_exchange = [exc for exc in clinker.biosphere()]
  clinker_bio_exchange
  </code></pre>
  
  <p>Error:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
