I try to implement the GOOGLE document AI API

Question

I try to implement the document AI API to be able to compare a document to see if it comes with phrases to know if the document is valid.

I am using nodejs to implement the document AI API, and the document I receive is a PDF that is sent through an input file

This is the error that I get:

Error: Error: 3 INVALID_ARGUMENT: Invalid resource field value in the request.

{
  code: 3,
  details: 'Invalid resource field value in the request.',
  metadata: Metadata {
    internalRepr: Map(4) {
      'endpoint-load-metrics-bin' => [Array],
      'grpc-server-stats-bin' => [Array],
      'google.rpc.errorinfo-bin' => [Array],
      'grpc-status-details-bin' => [Array]
    },
    options: {}
  },
  note: 'Exception occurred in retry method that was not classified as transient',
  statusDetails: [
    ErrorInfo {
      metadata: [Object],
      reason: 'RESOURCE_PROJECT_INVALID',
      domain: 'googleapis.com'
    }
  ],
  reason: 'RESOURCE_PROJECT_INVALID',
  domain: 'googleapis.com',
  errorInfoMetadata: {
    service: 'documentai.googleapis.com',
    method: 'google.cloud.documentai.v1.DocumentProcessorService.ProcessDocument'
  }
}

This is the code in nodejs that I use to authenticate myself and to make the comparison, I hope you can help me.

//documentAI

const { DocumentProcessorServiceClient } = require('@google-cloud/documentai').v1;

const keyFilename = path.join(__dirname,"../../src/credentials/documentApp.json");

// Configuración del cliente de Document AI
const client = new DocumentProcessorServiceClient({
  keyFilename: keyFilename,
});

async function procesarDocumentoConAI(document) {
    try {
        const request = {
            parent: 'projects/c26b6829b968a72c/locations/us',
            processorId:'c26b6829b968a72c',
            inputConfig: {
                content: document,
                mimeType: 'application/pdf',
              },
          };

        const [response] = await client.processDocument(request);

        if (response && response.text) {
            const text = response.text;
            const isINE = text.includes('INE') || text.includes('Instituto Nacional Electoral');

            if (isINE) {
                console.log('El documento contiene una INE mexicana.');
                return true;
            } else {
                console.log('El documento no contiene una INE mexicana.');
                return false;
            }
        } else {
            console.log('No se encontró texto en el documento.');
            return false;
        }
    } catch (error) {
        console.error('Error:', error);
    }
}

In your request, you are sending the processor ID as the project ID. You need to change it to be the project ID.

parent: 'projects/c26b6829b968a72c/locations/us',

c26b6829b968a72c is your Processor ID, this value should be changed to your project ID.

You can read how to find your project ID in this article.

Your request also isn't using the correct structure. You can find Node.JS sample code for making a processing request and information about how requests work on this page.
