I’m trying to get a code sample to use Azure Document Intelligence with files located on an in-house server but I’m getting the following error:

Azure.RequestFailedException: 'Resource not found
Status: 404 (Not Found)
ErrorCode: 404

Content:
{"error":{"code":"404","message":"Resource not found"}}

I’m following the steps provided in this articleGet started with Document Intelligence but I’ve adjusted it to use a local file instead of a uri.

This is my code:

string endpoint = "https://<MyServiceInstance>.cognitiveservices.azure.com/";
string apiKey = "<MyApiKey>";
string filename = "C:\..\MyFile.jpg";

var client = new DocumentIntelligenceClient(new Uri(endpoint), new AzureKeyCredential(apiKey));

using (FileStream stream = new FileStream(filename, FileMode.Open))
{
    var result = AnalyzeDocumentAsync(client, stream).GetAwaiter().GetResult();
    Console.WriteLine(result);
}


static async Task<Operation<AnalyzeResult>> AnalyzeDocumentAsync(
    DocumentIntelligenceClient client, 
    Stream documentStream)
{
    string modelId = "MyModelId";

    var content = new AnalyzeDocumentContent()
    {
         Base64Source = BinaryData.FromStream(documentStream)
    };

    var operation = await client.AnalyzeDocumentAsync(WaitUntil.Completed, modelId, content);

    AnalyzeResult result = operation.Value;

    Console.WriteLine($"Document was analyzed with model with ID: {result.ModelId}");

    foreach (AnalyzedDocument document in result.Documents)
    {
        Console.WriteLine($"Document of type: {document.DocType}");

        foreach (KeyValuePair<string, DocumentField> fieldKvp in document.Fields)
        {
            string fieldName = fieldKvp.Key;
            DocumentField field = fieldKvp.Value;

            Console.WriteLine($"Field '{fieldName}': ");

            Console.WriteLine($"  Content: '{field.Content}'");
            Console.WriteLine($"  Confidence: '{field.Confidence}'");
        }
    }

    return operation;
}

The line that’s throwing the exception is:

var operation = await client.AnalyzeDocumentAsync(WaitUntil.Completed, modelId, content);

I’m getting my settings from Azure as per instructed in article:

and my model is a “Custom Model” and I’m using the name of the Id I used when training the model.

Anyone has any ideas what I’m missing?
