aws-sdk-java-v2: LambdaConversionException: Invalid receiver type interface org.apache.http.Header; not a subtype of implementation type interface org.apache.http.NameValuePair

Hi there,

I’m trying to use the cloudsearchdomain service, especially the SwitchToPostInterceptor.

Expected Behavior

Using the CloudSearchDomainClient, I’m trying to upload documents to an existing instance. I expect an HTTP-Response with status code 200, which should be mapped to the Java type SearchResponse.

Current Behavior

Unfortunately, the mapping of the response to the Java type does not seem to work. The method call ends with the exception listed below:

Steps to Reproduce (for bugs)

In Maven POM (among other dependencies of [aws-sdk-java|https://github.com/aws/aws-sdk-java]):

        <dependency>
            <groupId>software.amazon.awssdk</groupId>
            <artifactId>cloudsearchdomain</artifactId>
            <version>2.0.0-preview-11</version>
        </dependency>

DomainClient configuration:

CloudSearchDomainClient.builder()
                .endpointOverride(URI.create(cs_document_endpoint))
                .credentialsProvider(cp)
                .build();

UploadDocument operation:

         JSONArray batch = ...;
         byte[] batchAsBytes = batch.toString().getBytes();
        RequestBody requestBody = RequestBody.fromBytes(batchAsBytes);

        UploadDocumentsRequest uploadDocumentsRequest = UploadDocumentsRequest.builder()
                .contentLength(Long.valueOf(batchAsBytes.length))
                .contentType(ContentType.APPLICATION_JSON)
                .build();

        UploadDocumentsResponse result = domain.uploadDocuments(uploadDocumentsRequest,
                requestBody);

Context

As mentioned above, I’m already using the aws-sdk-java CloudSearch client. However, I want to take advantage of the usage of POST as HTTP-Method for every request.
