Specifying entity type using Apache Olingo

I am using Apache Olingo v4 java library in my project and it works great. Thanks!

I am having issues calling one particular endpoint - 

https://learn.microsoft.com/en-us/dynamics365/customer-engagement/web-api/merge?view=dynamics-ce-odata-9

ISSUE : Cannot specify entity type in request. Cannot figure out if this has to be passed in as an annotation or what. I tried passing it in as a param but Library then appends its type as string param instead.

Expected request body to contain :

    "@odata.type": "Microsoft.Dynamics.CRM.account"

Actual request body contain : 

    "@[email protected]": "String", 
    "@odata.type": "Microsoft.Dynamics.CRM.account"

The above request is causing exception inside crm since they do not expect this param. 

An error occurred while validating input parameters: Microsoft.OData.ODataException: Does not support untyped value in non-open type.
  at System.Web.OData.Formatter.Deserialization.DeserializationHelpers.ApplyProperty(ODataProperty property, IEdmStructuredTypeReference resourceType, Object resource, ODataDeserializerProvider deserializerProvider, ODataDeserializerContext readContext)
  at System.Web.OData.Formatter.Deserialization.ODataResourceDeserializer.ApplyStructuralProperties(Object resource, ODataResourceWrapper resourceWrapper, IEdmStructuredTypeReference structuredType, ODataDeserializerContext readContext)
  at Microsoft.Crm.Extensibility.OData.CrmODataEntityDeserializer.ApplyStructuralProperties(Object resource, ODataResourceWrapper resourceWrapper, IEdmStructuredTypeReference structuredType, ODataDeserializerContext readContext)
  at System.Web.OData.Formatter.Deserialization.ODataResourceDeserializer.ReadResource(ODataResourceWrapper resourceWrapper, IEdmStructuredTypeReference structuredType, ODataDeserializerContext readContext)
  at Microsoft.Crm.Extensibility.OData.CrmODataActionPayloadDeserializer.ReadEntry(ODataDeserializerContext readContext, ODataParameterReader reader, IEdmOperationParameter parameter)
  at Microsoft.Crm.Extensibility.OData.CrmODataActionPayloadDeserializer.Read(ODataMessageReader messageReader, Type type, ODataDeserializerContext readContext)
  at System.Web.OData.Formatter.ODataMediaTypeFormatter.ReadFromStream(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger) [HTTP/1.1 400 Bad Request]

I have tried appending annotations to the object but those do not end up in request body.

For reference, following request body works using postman (plain old http client) :

{
    "Target": {
        "accountid": "b68c98c3-f339-e811-eeee-000d3a137a33",
        "@odata.type": "Microsoft.Dynamics.CRM.account"
    },
    "Subordinate": {
        "accountid": "f89a8c95-2353-e811-wwww-000d3a137896",
        "@odata.type": "Microsoft.Dynamics.CRM.account"
    },
    "UpdateContent": {
        "websiteurl": "testdata.com",
        "@odata.type": "Microsoft.Dynamics.CRM.account"
    },
    "PerformParentingChecks": "false"
}

Thanks in advance for taking time to help me.

Using Olingo client library could be chatty when trying to use the "type" system. Please check out code snippet below in groovy to see if it is helpful:

static AbstractODataInvokeRequest buildMergeRequest(ODataClient client, URI mergeUri,
        String targetLeadIdStr, String subLeadIdStr) {
    Map<String, ClientValue> params = [:]
    params.put("Target", buildEntityIdComplex(client, "leadid", targetLeadIdStr))
    params.put("Subordinate", buildEntityIdComplex(client, "leadid", subLeadIdStr))
    params.put("UpdateContent", buildEntityIdComplex(client, "leadid", "00000000-0000-0000-0000-000000000000"))
    params.put("PerformParentingChecks", client.getObjectFactory().newPrimitiveValueBuilder().buildBoolean(false))

    AbstractODataInvokeRequest funcReq =
            client.getInvokeRequestFactory().getActionInvokeRequest(mergeUri, ODataError.class, params)
                    .addCustomHeader("Authorization", "Bearer ${accessToken}")
    funcReq.setFormat(ContentType.JSON_NO_METADATA)
    return funcReq;
}

static ClientComplexValue buildEntityIdComplex(ODataClient client, String entityIdName, String entityIdValStr) {
    ClientComplexValue targetLeadId = client.getObjectFactory().
            newComplexValue("Microsoft.Dynamics.CRM.lead")
    targetLeadId.add(client.getObjectFactory().newPrimitiveProperty(entityIdName,
            client.getObjectFactory().newPrimitiveValueBuilder().buildGuid(buildKey(entityIdValStr))))
    targetLeadId.add(client.getObjectFactory().newPrimitiveProperty("@odata.type",
            client.getObjectFactory().newPrimitiveValueBuilder().buildString("#Microsoft.Dynamics.CRM.lead")))
    return targetLeadId
}

Noticed that:

  1. funcReq.setFormat(ContentType.JSON_NO_METADATA) to indicate JSON only format to send to server.
  2. From groovy to java, Intellij has a menu item to do that. Or you can manually add ";" and type most of the time.
