NonRepeatableRequestException Error during indexing after setting up Basic Authentication

[Zheng Lin Edwin Yeo <ed...@gmail.com>]

Hi,

I'm getting an error with indexing using SolrJ after setting up the Basic
Authentication with the following code.

Credentials defaultcreds = new UsernamePasswordCredentials("id",
"password");
appendAuthentication(defaultcreds, "BASIC", solr);

private static void appendAuthentication(Credentials credentials, String
authPolicy, SolrClient solrClient) {
//  if (isHttpSolrClient(solrClient)) {
  HttpSolrClient httpSolrClient = (HttpSolrClient) solrClient;

//   if (credentials != null && StringUtils.isNotBlank(authPolicy)
//     && assertHttpClientInstance(httpSolrClient.getHttpClient())) {
   AbstractHttpClient httpClient = (AbstractHttpClient)
httpSolrClient.getHttpClient();
   httpClient.getCredentialsProvider().setCredentials(new
AuthScope(AuthScope.ANY), credentials);
   httpClient.getParams().setParameter(AuthPNames.TARGET_AUTH_PREF,
Arrays.asList(authPolicy));
//   }
//  }
}


The is the error message that I got.

The error occurs at the part where I do the adding of the index to Solr

solr.add(batch);


This is what is defined for "solr".

static SolrClient solr;
solr = new HttpSolrClient( SOLR_URL );


What could be the reason for this? Is there anything wrong with my code?
I'm using SolrCloud on Solr 6.4.2.

Regards,
Edwin
