Getting HTTP error 400 Bad Request - Invalid URL when trying to update SharePoint field

Question

I am trying to update a field inside a Sharepoint document library using Apache HTTPClient, but keep getting HTTP error 400 - Invalid URL. The code and the output is as mentioned below. Please advise why this is happening

    public static boolean setFieldValue(CloseableHttpClient httpClient, String siteURL, String serverRelativeURL, String fieldName, String fieldValue) {

    CloseableHttpResponse httpResponse = null;

    try {
        URI siteURI = new URI(siteURL);
        URI postURI = new URIBuilder(siteURI)
                .setPath(siteURI.getPath() + "/_api/web/GetFileByServerRelativeUrl('" + serverRelativeURL + "')/ListItemAllFields")
                .build();
        HttpPost httpPost = new HttpPost(postURI);

        String formDigestValue = getFormDigestValue(httpClient, postURI);
        if (StringUtils.isBlank(formDigestValue)) {
            logger.error("FORM DIGEST VALUE IS = " + formDigestValue);
            return false;
        }

        httpPost.addHeader(ACCEPT, APPLICATION_JSON);
        httpPost.addHeader(CONTENT_TYPE, APPLICATION_JSON);
        httpPost.addHeader(X_HTTP_Method, MERGE);
        httpPost.addHeader(IF_MATCH, Punctuation.ASTERISK);
        httpPost.addHeader(X_REQUEST_DIGEST, formDigestValue);

        JSONObject jsonObject = new JSONObject();
        jsonObject.put(fieldName, fieldValue);
        jsonObject.put("__metadata", new JSONObject().put("type", "SP.Data.PuneetsLibraryItem"));
        logger.debug(jsonObject);

        httpPost.setEntity(new StringEntity(jsonObject.toString()));

        logger.trace(httpPost.getRequestLine());
        logger.trace(httpPost.getURI());

        httpResponse = httpClient.execute(httpPost);

        HttpEntity entity = httpResponse.getEntity();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(entity.getContent()));
        if (bufferedReader != null) {
            int cp;
            StringBuilder sb = new StringBuilder();
            while ((cp = bufferedReader.read()) != -1) {
                sb.append((char) cp);
            }
            logger.debug("String Response......." + sb);
            bufferedReader.close();
        }
        logger.debug("Response......." + entity.getContent());

        logger.trace(httpResponse.getStatusLine().getReasonPhrase());

        int status = httpResponse.getStatusLine().getStatusCode();
        if (status >= 200 && status < 300) {
            return true;
        } else {
            logger.error("ERROR: " + httpResponse.getStatusLine().toString().toUpperCase());
        }

    } catch (URISyntaxException | IOException e) {
        logger.error(e.getMessage(), e);
    } finally {
        try {
            if (httpResponse != null) {
                httpResponse.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return false;

}

I realized my mistake so I am posting an answer. The HttpClient was sending an expect header field in the request, which it shouldn't be sending. Also the X-Request-Digest had to be replaced by X-RequestDigest .

The way to turn off the expect header was as follows:

defaultRequestConfig = RequestConfig.custom()
        .setExpectContinueEnabled(false)
        .setTargetPreferredAuthSchemes(Arrays.asList(AuthSchemes.NTLM, AuthSchemes.DIGEST))
        .setProxyPreferredAuthSchemes(Collections.singletonList(AuthSchemes.BASIC))
        .build();

httpclient = HttpClients.custom()
        .setConnectionManager(httpClientConnectionManager)
        .setDefaultCredentialsProvider(credentialsProvider)
        .setDefaultRequestConfig(defaultRequestConfig)
        //.setConnectionTimeToLive(1, TimeUnit.MINUTES)
        .build();
