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.
