"No license found" after version update

[zorapeteri]

We are using barcode4nodejs in a Node project and have recently bumped it from 9.6.47 to 10.0.5. Unfortunately the barcode scanning process is now breaking, with the error message:

InitLicense: Successful.
StartCapturing: [Barcode Reader] [ONED] No license found.

I've double-checked the license code, and with the previous version it works just fine.

If I purposefully change the license code to an invalid one, this is what I get:

InitLicense: [License] [Key 1] The license is invalid.
StartCapturing: [Barcode Reader] No license found. [License] [Key 1] The license is invalid.

The JS code itself doesn't throw an error, just logs this to the console, and gracefully returns an empty array, so since the update we have been assuming that a lot of scanned documents just have no barcodes.

@zorapeteri Thank you for reaching out and providing detailed information about the issue you're experiencing with barcode4nodejs. It’s possible that the license key needs to be updated for v10. To test this, you can request a new trial license key. Additionally, please contact [email protected] to verify if your current license key is valid for v10. 😃

@zorapeteri I've made a test.

• All types: dbr.formats.ALL
  Code:

  dbr.decodeFileAsync("images/test.tif", dbr.formats.ALL, function (err, msg) {
      console.log(msg);
      for (index in msg) {
          result = msg[index];
          console.log('Format: ' + result['format']);
          console.log('Value : ' + result['value']);
          console.log('x1: ' + result['x1']);
          console.log('y1 : ' + result['y1']);
          console.log('x2: ' + result['x2']);
          console.log('y2 : ' + result['y2']);
          console.log('x3: ' + result['x3']);
          console.log('y3: ' + result['y3']);
          console.log('x4: ' + result['x4']);
          console.log('y4: ' + result['y4']);
          console.log('page: ' + result['page']);
          console.log('decoding time: ' + result['time']);
      }
  }, "");

  Output:

  PS D:\code\nodejs-barcode> node test.js
  Windows
  InitLicense: Successful.
  StartCapturing: [Barcode Reader] [ONED] No license found.

• DataMatrix only: dbr.formats.DATAMATRIX

  Code:

  dbr.decodeFileAsync("images/test.tif", dbr.formats.DATAMATRIX, function (err, msg) {
  console.log(msg);
  for (index in msg) {
      result = msg[index];
      console.log('Format: ' + result['format']);
      console.log('Value : ' + result['value']);
      console.log('x1: ' + result['x1']);
      console.log('y1 : ' + result['y1']);
      console.log('x2: ' + result['x2']);
      console.log('y2 : ' + result['y2']);
      console.log('x3: ' + result['x3']);
      console.log('y3: ' + result['y3']);
      console.log('x4: ' + result['x4']);
      console.log('y4: ' + result['y4']);
      console.log('page: ' + result['page']);
      console.log('decoding time: ' + result['time']);
  } }, "");

  Output:
