Mapping configuration are as follows:

```auto
es_mapping = {
            'properties': {
                'university': {
                    'type': 'object',
                    'properties': {
                        'name': {'type': 'text'},
                    }
                },
                'first_name': {'type': 'text'},
                'last_name': {'type': 'text'},
                'age': {'type': 'short'},
                'year_in_school': {'type': 'text'},
                'name_complete': {
                    'type': 'completion', # you have to make a method for completition for sure!
                    'analyzer': 'simple',
                    'payloads': True, # note that we have to provide payload while updating
                    'preserve_separators': True,
                    'preserve_position_increments': True,
                    'max_input_length': 50,
                },
                "course_names": {
                    "type": "text", 
                },
            }

```

Using above mapping when script is getting executed it gives following error:  
Error:  
elasticsearch.exceptions.RequestError: TransportError(400, u'mapper\_parsing\_exception', u'Mapping definition for [name\_complete] has unsupported parameters: [payloads : true]')

By commenting this mapping I tried to run script but it fails while loading data with the following error:  
u'error': {u'caused\_by': {u'reason': u'unknown field name [payload], must be one of [input, weight, contexts]', u'type': u'illegal\_argument\_exception'}, u'reason': u'failed to parse', u'type': u'mapper\_parsing\_exception'}

Hi,

_a general tip with the forum: please enclose code snippets in "```" otherwise the snippet is very hard to read. I edited your question so it is properly formatted._

You define the `name_complete` field to be used with a completion suggester, however you are using an unsupported parameter `payloads` (see [docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters-completion.html)) so the fix is to remove that parameter.

Daniel

Got it, Thank you Daniel.
