Hi I am using java high level rest api client to read some documents from an elastic search index and i am getting the following error .

I get this error when i do perform a request on elasticsearch client as below.

elasticSearchClient.search(searchRequest, RequestOptions.DEFAULT);

```auto

You can't provide a `java.util.UUID` value. You should provide a string representation of the uuid by invoking its toString() method.

this is my code ,.. where should i change the UUID thing

According to the stack trace this error occurs in a match query and there are few match queries  
in your code. Only for cdr status and inventory code the toString() is not invoked, assuming that inventory code is some sort of an id, I'd guess you need to change:

```auto
MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("inventory",

messageHistoryFilterRequest.getInventoryCode());

```

to

```auto
MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("inventory",

messageHistoryFilterRequest.getInventoryCode().toString());

```
