Thread: Need help in a java script

I am a beginner in java scripting . Requirement is to create a ticket in dynamics 365.The data is available in a relational table and i am initially writing a java code where i can manually pass the values in the json input and create a ticket.
After i pass the api and the client id ,client secret and tenant id it would generate a token and based on input of the body will create a ticket (not sure if my code is working on this functionality).

import com.microsoft.aad.adal4j.AuthenticationResult;
import com.microsoft.aad.adal4j.ClientCredential;

public class javacodedynamics365 {
    public static void main(String[] args) {
 
        String authority = "https://login.microsoftonline.com/";
        String resource = "https://lenovo-nitro-uat.crm.dynamics.com";
        String clientId = "";
        String clientSecret = "";
        String tenantID = "";
        ExecutorService service = Executors.newFixedThreadPool(1);
        AuthenticationResult result;
 
        try {
            AuthenticationContext context = new AuthenticationContext(authority + tenantID, true, service);
            Future<AuthenticationResult> future = context.acquireToken(resource, new ClientCredential(clientId, clientSecret), null);
 
            result = future.get();
            String accessToken = result.getAccessToken();
            System.out.println(accessToken);
 
            createWithDataReturned(accessToken);
        }
        catch (MalformedURLException e) { }
        catch (InterruptedException e) { }
        catch (ExecutionException e) { }
    }

        try {
            OkHttpClient client = new OkHttpClient();
 
 
            MediaType mediaType = MediaType.parse("application/json; charset=utf-8");
            System.out.println(mediaType);
            RequestBody body = RequestBody.create(mediaType, "{" +
                   "\"Account_Alias_Request\": \"Knot Technology Solutions LLC\"" +
                    "\"Partner_MDM_ID\": \"PA000000900211\"" +
                    "}");
            Request request = new Request.Builder()
                    .url("https://lenovo-nitro-uat.crm.dynamics.com/api/data/v9.1/lvo_DSRAccountReview")
                    .post(body)
                    .addHeader("OData-MaxVersion", "4.0")
                    .addHeader("OData-Version", "4.0")
                    .addHeader("Accept", "application/json")
                    .addHeader("Content-Type", "application/json; charset=utf-8")
                    .addHeader("Prefer", "odata.include-annotations=\"*\"")
                    .addHeader("Authorization", "Bearer " + accessToken)
                    .addHeader("cache-control", "no-cache")
                   // .addHeader("Postman-Token", "a3ca1261-85fe-4b57-84e0-034e0d582d46")
                    .build();
   		 System.out.println(request);
Response response = client.newCall(request).execute();
String dataReturnedFromCreate = response.body().string();
System.out.println(dataReturnedFromCreate);
 
            System.out.println();
       }
       catch (Exception e) { }
   }
}

the above code is returning the token. But gives the error on
Request{method=POST, url=https://lenovo-nitro-uat.crm.dynamics.com/api/data/v9.1/lvo_DSRAccountReview, tags={}}
{"error":{"code":"0x0","message":"An error occurred while validating input parameters: System.ArgumentException: Stream was not readable.\r\n at System.IO.StreamReader..ctor(Stream stream, Encoding encoding, Boolean detectEncodingFromByteOrderMarks, Int32 bufferSize, Boolean leaveOpen)\r\n at System.IO.StreamReader..ctor(Stream stream, Encoding encoding)\r\n at Microsoft.OData.JsonLight.ODataJsonLightInputConte xt.CreateTextReader(Stream messageStream, Encoding encoding)\r\n at Microsoft.OData.JsonLight.ODataJsonLightInputConte xt..ctor(ODataMessageInfo messageInfo, ODataMessageReaderSettings messageReaderSettings)\r\n at Microsoft.OData.Json.ODataJsonFormat.CreateInputCo ntext(ODataMessageInfo messageInfo, ODataMessageReaderSettings messageReaderSettings)\r\n at Microsoft.OData.ODataMessageReader.ReadFromInput[T](Func`2 readFunc, ODataPayloadKind[] payloadKinds)\r\n at Microsoft.Crm.Extensibility.ODataV4.CrmODataAction PayloadDeserializer.Read(ODataMessageReader messageReader, Type type, ODataDeserializerContext readContext)\r\n at System.Web.OData.Formatter.ODataMediaTypeFormatter .ReadFromStream(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)"}}
