Notice that under your qrcode-gen node it says Error: see details in debug win?

Add a debug node to the output of the ui-form node (Datos_Ingreso) to see what is being sent into the qrcode-gen node. Then click on the qrcode-gen node and look at the help tab (in the sidebar and looks like a book) for the node.

  • What is it looking for as input?
  • Are you sending the data in the way the node needs it?

You might want to add the node 'node-red-contrib-image-output` to the flow so you can see the generated image in the editor.
