[GeorgeAp]

Elasticsearch version (bin/elasticsearch --6.8.2)

JVM version (1.8.0_242)

OS version (18.04.1-Ubuntu)

Description of the problem including expected versus actual behavior:
Running the query below yields NullPointException on a one node cluster indexed with two documents.

curl -H'Content-Type: application/json' -XGET "localhost:9200/_search?pretty" -d '
{
  "query": {
    "bool": {
      "filter": [
        {
          "span_near": {
            "clauses": [
              {
                "span_term": {
                  "description":"deposition"
                }
              },
              {
                "span_multi": {
                  "match": {
                    "fuzzy": {
                      "description": {
                        "value": "foobarbaz"
                      }
                    }
                  }
                }
              }
            ]
          }
        }
      ]
    }
  }
}'

Documents used
I indexed the two documents below on the single node.

2. Execute the query above.
3. NullPointException occurs on every run.
