title: No async queries in azure blob trigger
body: <p>I'm using this function in inside an azure blob trigger:</p>
  <pre><code>## decompose and save a csv file from a gz
  def handle_csv_gz(data,name_bucket,separateur,table_name,nb,chunk,name_columns,row_to_skip,enco,schema_name):
  logging.info(&quot;decompose and save a csv file from a gz&quot;)
  
  logging.info(&quot;decompress the data with gzip&quot;)
  data = gzip.GzipFile(fileobj=io.BytesIO(data.raw.read()))
  logging.info(&quot;data decompressed!&quot;)
  
  logging.info(&quot;read csv file&quot;)
  df_chunk = pd.read_csv(data,chunksize = 
  chunk,sep=separateur,engine='python',names=name_columns,skiprows=row_to_skip,encoding=enco)
  logging.info(&quot;csv have been read&quot;)
  for df in df_chunk:
      logging.info(&quot;loop for&quot;)
      if (len(df) &gt; 0):
          logging.info(&quot;nb = &quot; + str(nb))
          nb = nb + 1
          handle_df_chunk(df,name_columns,name_bucket,schema_name,table_name,nb)
  logging.info(&quot;file decomposed successfully&quot;)
  return nb
  </code></pre>
  <p>And I'm getting an error in the for loop: No async queries seem to be running, deleting session.
  I have this error just when I'm using the serverless azure functions, when I run a local version in my vs code it works.</p>
  <p>Thank you</p>
