Markdown card

Hello,

can someone explain to me why the following code won’t work?

I have installed the f1 addon in my home assistant.
Now I want to add the following code to the markdown card.

<img width="100%" src="https://www.formula1.com/content/dam/fom-website/2018-redesign-assets/Circuit%20maps%2016x9/{{nr.Circuit.Location.country|replace(' ','_')}}_Circuit.png.transform/7col/image.png">

It must show the f1 circuit but I don’t see any image.
When I put just <img src="https://cdn.pixabay.com/photo/2015/04/19/08/32/marguerite-729510__480.jpg"> then I see the flower image.

What am I missing or doing wrong?
