Get the above exception when I try to use and run the below api.

	 CosmosAsyncClient	 client = new CosmosClientBuilder()
			                              .endpoint(endpointUri)
			                              .key(connection_string)
			                             .buildAsyncClient();

public String connection_string = "AccountEndpoint=https://";

Is that conneciton_string needs to be encrypted ? but how it has to be ?
