Document intelligence didn't work after deployment to azure

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"}}

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