   I patched our local deployment with the following in the function mentioned above:
   Replaced
   ```
               if row_data and len(row_data) != len(row_children):
                   raise Exception(
                       "The number of data values and number of nested"
                       "fields are not equal"
                   )
   ```
   
   with 
   
   ```
   if row_data and len(row_data) != len(row_children):
                   for index, data_value in enumerate(row_data):
                       if index >= len(row_children):
                           row_children.append("col_{}".format(index))
                       datum[row_children[index]] = data_value
   ```
