Siren + Senzing Integration: Data not appearing in Elasticsearch

I am currently working through evaluation of the Siren+Senzing Integration as shown here:

https://docs.support.siren.io/siren-er/2.0.0/siren-er/siren-er-getting-started.html

Everything seems fine until step 6:

" 6. Run Logstash to update Elasticsearch with updated data from PostgreSQL"

When I carry out the chec: “Check there are entity records in Elasticsearch:” in the Dev Tools section of the Siren Investigate dashboard:

“GET entity2record/_search”

I don’t see any of the data being returned from elasticsearch, just an empty data structure json:

  "took" : 0,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "entity2record",
        "_type" : "_doc",

        "_score" : 1.0,
        "_ignored" : [
          "entity_rels_deletes_query.keyword"
        ],
        "_source" : {

          "entity_rels_deletes_query_response" : {

          "task_id" : "senzing",
          "entity_rels_deletes_query" : """{"query": {"bool": {"should": [ {"bool": {"should": [ {"terms":{"min_res_ent_id": [  ] }}, {"terms": {"max_res_ent_id": [  ]}} ]}}, {"bool": { "should": [ {"terms": {"min_res_ent_id": [  ]}}, {"terms": {"max_res_ent_id": [  ]}}], "must_not": {"ids": {"values": [ "-" ]}}}}]}}}"""
        }
      }
    ]
  }
}

Please can you provide some steps I could use to troubleshoot in more detail why the data hasn’t ended up in this index?

Hi Traiano,
