Document intelligence didn't work after deployment to azure

Question

I have asp.net web app with following code which works in local system (Mac OS) but didn't work in Azure Web App (Linux) after deployment.

I checked the api key and api endpoint with logging and they are correct.

I'm using Azure.AI.DocumentIntelligence" Version="1.0.0-beta.3"

 async Task<AnalyzeDocumentResult> AnalyzeDocumentAsync(string filePath)
 {
 var config = ((IConfigurationRoot)_config).GetRequiredSection("DocumentIntelligence").Get<DocumentIntelligenceConfig>();
 var credential = new AzureKeyCredential(config?.ApiKey ?? string.Empty);
 var options = new DocumentIntelligenceClientOptions(DocumentIntelligenceClientOptions.ServiceVersion.V2024_07_31_Preview);
 var client = new DocumentIntelligenceClient(new Uri(config?.EndPoint ?? string.Empty), credential, options);
 var file = new AnalyzeDocumentContent()
 {
 Base64Source = BinaryData.FromBytes(await File.ReadAllBytesAsync(filePath))
 };
 var operation = await client.AnalyzeDocumentAsync(WaitUntil.Completed, "prebuilt-layout", file.Content, outputContentFormat: ContentFormat.Markdown);
 if (!operation.HasValue)
 {
 _logger.LogError($"File doesn't have data: trackingCode: {trackingCode}");
 return new AnalyzeDocumentResult(false, file.FilePath, null);
 }
 if (!operation.HasCompleted)
 {
 _logger.LogError($"File doesn't completed: trackingCode: {trackingCode}");
 return new AnalyzeDocumentResult(false, file.FilePath, null);
 }
 await File.WriteAllTextAsync(file.FilePath.Replace(".pdf", ".md"), operation.Value.Content);
 return new AnalyzeDocumentResult(true, file.FilePath, operation.Value.Content);
 }

I receive the following error:

AnalyzeFileAsync -> Resource not found
Status: 404 (Not Found)
ErrorCode: 404
Content:
{"error":{"code":"404","message":"Resource not found"}}
Headers:
Date: 2024年10月01日 20:43:28 GMT

Content-Type: application/json

It's really weird, why it should works locally but not after publish! What is the difference?

Answer 1

Yes, the problem you encoutred is due to deploying Doc Intelligence in unsupported Azure region.

It's specified in the Azure AI Document Intelligence documentation that the 2024年07月31日-preview version is currently available only in the following Azure regions:

• East US
• West US2
• West Europe
• North Central US

Answer 2

I'm not sure if this is directly related to this repository, but the issue I encountered was with the Germany West Central region. After redeploying Doc Intelligence in West Europe, everything is working fine now!

I couldn't find any documentation explaining the differences or specific issues between regions. If anyone else is facing a similar problem, consider redeploying to a different region, as it might resolve the issue.
