In new version mapping type was removed https://www.elastic.co/guide/en/elasticsearch/reference/6.7/removal-of-types.html

need to change mapping

    'mappings': {
        'speechanalytics-transcript': {
         'properties': {
           'transcript_operator':{
              'type': 'text',
              'analyzer': 'standard',
             'similarity': 'scripted_tfidf',
           }
          }
       }
    }

to

    'mappings': {
         'properties': {
           'transcript_operator':{
              'type': 'text',
              'analyzer': 'standard',
             'similarity': 'scripted_tfidf',
           }
        }
    }
