Hi @Akhil_parmar. Can you paste the stack trace from your elasticsearch logs? Also, what request were you making at the time of the error?

I was making an index request,  
StackTrace:  
org.elasticsearch.hadoop.rest.EsHadoopRemoteException: illegal\_argument\_exception: value for key [X-Opaque-Id] already present  
{"index":{"\_id"::123"}}  
{"id":"123", "name":"abc"}

We are using open source version of Elasticsearch hosted on private cloud.

I could see that X-Opaque-id header was added in 7.16.0 version.  
To resolve the issue I downgraded the ES spark SDK

```auto
<!-- https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-spark-30 -->
<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch-spark-30_2.12</artifactId>
    <version>7.15.0</version>
    <scope>provided</scope>
</dependency>

```
