Invalid NEST response built from a unsuccessful low level call on POST Error when the same series of nest and elastic search used

Question

I want to configure elastic client (NEST V7.17.5) on .net core.The version of elastic search used is V7.11.2. I configured the elastic search connection settings using the code below [Extension class](https://i.stack.imgur.com/bBNY8.png) I added the service in startup using the code below enter image description here Now on trying to search a user using elastic search am getting an error `Invalid NEST response built from a unsuccessful () low level call on POST: /users/_search?pretty=true&typed_keys=true

Audit trail of this API call:

Request:

<Request stream not captured or already read to completion by serializer. Set DisableDirectStreaming() on ConnectionSettings to force it to be set on the response.>

Response:

<Response stream not captured or already read to completion by serializer. Set DisableDirectStreaming() on ConnectionSettings to force it to be set on the response.> `
