Azure DocumentIntelligence Java SDK returning 404

Question

I am playing around with Azure's DocumentIntelligence service and I am trying to create a simple example using their Java SDK as mentioned in this piece of documentation. I have created a very minimal code example just to get a feel for it, only attempting to get paragraphs out of the document in question. The code sample is the following:

public class DocumentIntelligenceApp {

    private static final String ENDPOINT = System.getenv("DOCUMENT_INTELLIGENCE_ENDPOINT");
    private static final String KEY      = System.getenv("DOCUMENT_INTELLIGENCE_KEY");
    private static final String MODEL_ID = "prebuilt-layout";

    public static void main(String... args) {

        try {
            var client = new DocumentIntelligenceClientBuilder()
                    .credential(new AzureKeyCredential(KEY))
                    .endpoint(ENDPOINT)
                    .buildClient();

            var request = new AnalyzeDocumentRequest().setUrlSource("https://s29.q4cdn.com/175625835/files/doc_downloads/test.pdf");

            var poller = client.beginAnalyzeDocument(MODEL_ID,
                    null,
                    null,
                    null,
                    null,
                    null,
                    null,
                    request);

            var res = poller.getFinalResult();

            res.getParagraphs().forEach(documentParagraph -> {
                System.out.println("Paragraph: ");
                System.out.println(documentParagraph.getContent());
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

 }

Whenever I try to run this though I am met with the following exception:

com.azure.core.exception.ResourceNotFoundException: Status code 404, "{"error":{"code":"404","message":"Resource not found"}}"

I have tried searching for this online but I haven't found anything relevant yet. For reference I am using the latest version of the SDK com.azure:azure-ai-documentintelligence:1.0.0-beta.3.

Any ideas would be welcome.

Answer 1

For me the problem was having my resource in the wrong location.

With the Python SDK "Sweden Central" worked just fine, but with the Java Preview version I had to create a new resource in "West Europe", as mentioned in the "MS-Q&A" thread linked by Venkatesen.

Azure DocumentIntelligence Java SDK returning 404

I followed this MS-Document and downloaded the dependency with same package azure-ai-documentintelligence:1.0.0-beta.3.

Pom.xml

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-ai-documentintelligence</artifactId>
    <version>1.0.0-beta.3</version>
</dependency>

Using the below code with same PDF URL, I can be able to analyze the pdf url using Azure DocumentIntelligence Java SDK.

Code:

public class App {

    private static final String ENDPOINT = "https://venkatintelligence1.cognitiveservices.azure.com/";
    private static final String KEY      = "401a3644aca64c90976298576f79cc0b";
    private static final String MODEL_ID = "prebuilt-layout";

    public static void main(String... args) {

        try {
           DocumentIntelligenceClient documentIntelligenceClient = new DocumentIntelligenceClientBuilder()
            .credential(new AzureKeyCredential(KEY))
            .endpoint(ENDPOINT)
            .buildClient();;
        
        SyncPoller<AnalyzeResultOperation, AnalyzeResult> Poller =
            documentIntelligenceClient.beginAnalyzeDocument(MODEL_ID,
                null,
                null,
                null,
                null,
                null,
                null,
                new AnalyzeDocumentRequest().setUrlSource("https://s29.q4cdn.com/175625835/files/doc_downloads/test.pdf"));

                AnalyzeResult analyzeResult = Poller.getFinalResult();

                analyzeResult.getParagraphs().forEach(documentParagraph -> {
                System.out.println("Paragraph: ");
                System.out.println(documentParagraph.getContent());
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Output:
