when I try to use my api I cant find the modelId, it wants a GUID but my custom model has a custom name.

Hi, If you're using v3.x then the model custom name is the modelID.

Where do I find my custom modelId for Azure Form Recognizer? (Document Intelligence?)

Hi @HouMez , thanks for the reply, I tried to use my custom model name in my C# app, but I get the following error:

{
  "data": null,
  "status": false,
  "code": 500,
  "message": "The modelId must be a valid GUID. (Parameter 'modelId')"
}

I even tried to clone my custom model and name it with a GUID, but I get this error:

{
  "data": null,
  "status": false,
  "code": 500,
  "message": "Specified model not found or not ready, Model Id: [MODEL-ID]\r\nStatus: 400 (Bad Request)\r\nErrorCode: 1001\r\n\r\nContent:\r\n{\"error\":{\"code\":\"1001\",\"message\":\"Specified model not found or not ready, Model Id: [MODEL-ID]\"}}\r\n\r\nHeaders:\r\nx-envoy-upstream-service-time: 85\r\napim-request-id: 485bb87c-d0fa-44bf-900d-7d0a74fdeaa2\r\nStrict-Transport-Security: max-age=31536000; includeSubDomains; preload\r\nX-Content-Type-Options: nosniff\r\nx-ms-region: REDACTED\r\nDate: Tue, 05 Sep 2023 12:07:48 GMT\r\nContent-Length: 124\r\nContent-Type: application/json; charset=utf-8\r\n"
}

Hi Felipe,

I was referring to the REST API, my bad.
For C#, I suggest double checking the version of the SDK you're using, the latest one require the model name instead of a GUID. More infos here.

Thanks!, I finally made it work, in case someone is having this same problem I will post my code here:

using System;
using System.IO;
using System.Net.Http;
using System.Threading.Tasks;
using Azure;
using Azure.AI.FormRecognizer;
using Azure.AI.FormRecognizer.Models;
using Microsoft.Extensions.Configuration;
using api_traductor.Utils;

using Response = api_traductor.Utils.Response;
using Azure.AI.FormRecognizer.DocumentAnalysis;

namespace api_traductor.Servicios.FormRecognizer
{
    public class FormRecognizerService
    {
        private readonly DocumentAnalysisClient client;

        public FormRecognizerService(IConfiguration configuration)
        {
            var endpoint = configuration["AzureFormRecognizer:Endpoint"];
            var apiKey = configuration["AzureFormRecognizer:ApiKey"];

            AzureKeyCredential credential = new AzureKeyCredential(apiKey);
            client = new DocumentAnalysisClient(new Uri(endpoint), credential);
        }

        public async Task<Response> AnalizarDocumento(string base64Data)
        {

            // Convertir el base64 a un arreglo de bytes
            byte[] bytes = Convert.FromBase64String(base64Data);
            using var stream = new MemoryStream(bytes);

            try
            {
                //modelo a utilizar y stream de la imagen a analizar.
                AnalyzeDocumentOperation operation = await client.AnalyzeDocumentAsync(WaitUntil.Completed, "RecognizerGeneral-V2.1", stream); //modelo a utilizar: RecognizerGeneral-V2.1, stream = imagen a analizar
                await operation.WaitForCompletionAsync();
                //asignamos a resulData el valor de la operación de analisis de documento
                AnalyzeResult resulData = operation.Value;

                //aqui podemos procesar los formularios reconocidos, extraer información que nos interese, ignorar la que no, etc. para asi moldear una respuesta acorde a nuestras necesidades.
                //por ahora, solo se envia el json completo como respuesta.
                var response = new Response
                {
                    Data = resulData,
                    Status = true,
                    Code = 200,
                    Message = "Analisis completo."
                };

                return response;
            }
            catch (Exception ex)
            {
                var response = new Response
                {
                    Data = null,
                    Status = false,
                    Code = 500,
                    Message = ex.Message
                };

                return response;
            }
        }
    }
}

the GetCustomModel() method requires a GUID.
