Delete Bitbucket Branch using Rest API in Java

[ramachandranp]

Trying to delete bibucket branch using rest api but always getting 405 or 145 or 500 as response code. Given below code snippet. Please guide!

String endPoint = "BASE_URL/rest/branch-utils/1.0/projects/<PROJECT>/repos/<REPO>/branches";
String requestJson = "{\"name\":\"refs/heads/feature/TEST\",\"dryRun\":\"false\"}";
HttpClient client = HttpClientBuilder.create().build();
HttpPut putRequest = new HttpPut(endPoint);
putRequest.addHeader("accept", "application/json");
putRequest.addHeader(AUTHORIZATION, BASIC + "passwordencrypted");

StringEntity input = new StringEntity(requestJson, StandardCharsets.UTF_8);
input.setContentType("application/json");
putRequest.setEntity(input);

HttpResponse response = client.execute(putRequest);
System.out.println("StatusCode :: " + response.getStatusLine().getStatusCode());

BufferedReader br = new BufferedReader(new InputStreamReader((response.getEntity().getContent())));
String output;
StringBuffer result = new StringBuffer();
while ((output = br.readLine()) != null) {
result.append(output);
}
System.out.println("FINAL :: " + result.toString());

Also tried with Postman, below errors. Any help will be appreciated!

{
"errors": [
{
"context": null,
"message": "An error occurred while processing the request. Check the server logs for more information.",
"exceptionName": null
}
]
}
