Embedded ES instance failing when running unit tests

I currently have the following code. The following is setting up a local elasticsearch instance using the elastic4s library

val essettings = Settings
  .settingsBuilder().put("cluster.name", "elasticsearch")
  .put("path.home", "/tmp/v").build()

ElasticsearchConnection.setInstance(ElasticClient.local(essettings))

val mockESItem1 = Map("title" -> "Worth It",
  "artist" -> "Fifth Harmony",
  "countries" -> Seq("AI", "CA", "IT", "AU", "GB", "IO", "IE", "GI", "US", "SH", "MS", "KY"),
  "thumbnails" -> Seq(Map("default" -> "http://ift.tt/1m57IIN")),
  "videoId" -> "VEVOID1", 
  "videoType" -> "type", 
  "ytVideoId" -> "YTID1", 
  "features" -> Seq(),
  "duration" -> 230)

Here I am creating a new index and then inserting the mockES item above.

client.execute( create index "videos" shards 1 replicas 5 mappings(
  "video" as (
    "artist" typed StringType,
    "title" typed StringType,
    "countries" typed StringType,
    "thumbnails" typed ObjectType,
    "videoId" typed StringType,
    "videoType" typed StringType,
    "ytVideoId" typed StringType,
    "features" typed StringType,
    "duration" typed IntegerType
    )
  )
)

client.execute(
  bulk(
    index into "videos"/"video" id 1 fields mockESItem1
  )
).await

However if I then run a query to find that item in any of my tests, similar to the following:

es.execute {
  search in "videos" / "video" limit 5 query bool {
    must(
      queryStringQuery("Worth It").field("title"),
      queryStringQuery("Fifth Harmony").field("artist").field("features"),
      matchQuery("videoType","type"),
      matchQuery("countries","US")
    )
  }
}.await

The program breaks with the following error:

org.elasticsearch.action.NoShardAvailableActionException: null

I've been trying to find a solution to this issue off and on for a few days and haven't been able to find anything that helps me solve this issue, so now looking to see if anyone on SE has had similar issues and found a fix.
