URL from attribute in QR Code Not shown

Configuration Frontend
1

Hi,

I created, with Feedparser, an entity to receive news from an RSS address. Besides the news itself, I would like to show a QR code with the URL of the news. I tried multiple solutions, but nothing worked as expected.

Version 1 doesn’t show a qr code:

type: custom:config-template-card
variables:
  # Verwende den YAML multiline Indikator '>' oder '|' und Quotes
  urllink: >
    {{ state_attr('sensor.rss_feed_ntv', 'entries')[0].link }}
entities:
  - sensor.rss_feed_ntv
card:
  type: custom:qr-code-card
  source: text
  # Stelle sicher, dass die Variable korrekt referenziert wird
  text: ${urllink}

Version 2 shows a qr code but the qr code contains the code as string instead of the url.

type: custom:config-template-card
entities:
  - sensor.rss_feed_ntv
card:
  type: custom:qr-code-card
  source: text
  # Verwende den YAML multiline Indikator '>' oder '|' und Quotes
  text: >
    {{ state_attr('sensor.rss_feed_ntv', 'entries')[0].link }}

Can someone help me?
