Response body not parsed for 202 -- doesn't match HTTP spec or Graph API behavior

When the response code of an API call is 202 Accepted, then CoreHttpProvider calls handleEmptyResponse(), which ignores the response body.

This causes the copyNotebook operation in the microsoft-graph jar to return an OnenoteOperation object with all null properties, and so the id can't be used to query the operation's status.

The HTTP spec for 202 says "The representation sent with this response ought to describe the request's current status and point to (or embed) a status monitor that can provide the user with an estimate of when the request will be fulfilled." so I believe the API itself is behaving correctly/within the spec and that it is this project that is incorrectly assuming that a 202 response will not have any body content.

Expected behavior

graphClient.sites(site.id).onenote().notebooks(notebook.id).copyNotebook(params).buildRequest().post(); returns a OnenoteOperation with fields populated from the response body.

Actual behavior

graphClient.sites(site.id).onenote().notebooks(notebook.id).copyNotebook(params).buildRequest().post(); returns a OnenoteOperation with all fields set to null.

Steps to reproduce the behavior

SiteRequestBuilder siteRequestBuilder = graphClient.sites(site.id);
OnenoteOperation operation = siteRequestBuilder.onenote().notebooks(notebook.id).copyNotebook(params).buildRequest().post();
// operation.id is null here, so the following line fails:
operation = siteRequestBuilder .onenote().operations(operation.id).buildRequest().get();

we are still experiencing the issue. Is there an ETA on addressing it?

According to the API documentation at the link below, the API does not return a response body for this call hence the null values in the response.

Any chance you can check the response headers for the same and confirm if the Operation-Location header is present to use for the checking the status of the operation?

That is not accurate. When sending a configure POST request to Graph, API, in fact, returns an asynchrony job identifier, job status and some high level schema validation. You can locate the schema for the response if you make a call through a postman. I can also send you a schema during my work hours tomorrow.

Operation location header is indeed present, but there is no way to extract it buy the time the response reaches Graph Java SDK. On Mon, Jan 23, 2023 at 10:54 PM Lev David Gorbunov ***@***.***> wrote:

This is a new API pattern that all the SDKs would need to implement a task for (like batching, large file upload...)
We currently don't have a design for it, but a task to create the design has been created here microsoftgraph/msgraph-sdk-design#83

This workaround is ugly, but it works:

NotebookCopyNotebookRequestBuilder notebookRequestBuilder = graphClient.onenote().notebooks(notebookId).copyNotebook(params);
IHttpRequest iHttpRequest = notebookRequestBuilder.buildRequest().withHttpMethod(HttpMethod.POST);

// Can't use a lambda because generateResult has type parameters
// https://docs.oracle.com/javase/specs/jls/se8/html/jls-15.html#jls-15.27.3
IStatefulResponseHandler<OnenoteOperation, OnenoteOperation> handler = new IStatefulResponseHandler<OnenoteOperation, OnenoteOperation>() {
	@Override
	public <T> OnenoteOperation generateResult(IHttpRequest request, T response, ISerializer serializer, ILogger logger) throws Exception {
		if (!(response instanceof Response)) {
			throw new ClientException("unsupported response type", null);
		}
		final Response nativeResponse = (Response) response;

		if (nativeResponse.code() >= HttpResponseCode.HTTP_OK
			&& nativeResponse.code() < HttpResponseCode.HTTP_MULTIPLE_CHOICES) {
			try (final ResponseBody body = nativeResponse.body()) {
				final byte[] responseBytes = body.bytes();
				return serializer.deserializeObject(new ByteArrayInputStream(responseBytes), OnenoteOperation.class);
			}
		} else {
			throw new ClientException("Non-2xx response " + nativeResponse.code() + ": " + nativeResponse.body().string(), null);
		}
	}
};
OnenoteOperation operation = notebookRequestBuilder.getClient().getHttpProvider().send(iHttpRequest, OnenoteOperation.class, params, handler);

From there you can update the status in a loop via:

operation = graphClient.onenote().operations(operation.id).buildRequest().get();

However, I've noticed that as soon as the operation is complete this call begins to return an error (20112 "Invalid Entity ID specified"). It's as if the server immediately forgets about the job so that you can never actually see the "complete" status. I'm handling this by catching the exception and treating it like success:

try {
	operation = graphClient.onenote().operations(operation.id).buildRequest().get();
} catch (GraphServiceException e) {
	GraphError error = e.getError().error;
	if (operation.id != null && StringUtils.equals(error.code, "20112")) {
		// 20112 = "Invalid Entity ID specified".
		// This happens if the server is no longer tracking this operation, which happens pretty quickly after the operation completes.
		break;
	} else {
		throw e;
	}
}

Again: ugly but it works.

david-burke-securian Thank you for pointing out the workaround! While we already have created our custom HTTP client to make requests to the API directly (and not via SDK since it's broken), I feel like having this ugly workaround mentioned anywhere in documentation would have saved us 4 days of debugging and development work. Another issue worth mentioning is that if you put a json string into a post request's body an empty 502 bad gateway error is returned.

Vincent Biret (@baywet) thank you for pointing out the changes in the API. Just to confirm, does it mean that the response body for the configure post request will go away soon? please advise.

Raised https://github.com/microsoftgraph/microsoft-graph-docs/issues/19997 for the documentation to be followed up.

Thank you! Also keep in mind that since currently the successful POST request returns HTTP 204, the response body is being omitted by the SDK

To answer your question from earlier, no it wouldn't disappear, it'd just mean we'd make available what we call a "task" in our design language that'd do the polling for you and give you the result. Kind of like batching support today. But again this is probably a long way out, after the next major release of this SDK.

Oh that would be cool, thanks!
