With that code works fine
It seems you have an issue with the style, the nodeicon.less is empty. Please check if t here is any issue.
For a quickfix add this temporary to your extra.less
CSS:.node-icon { .cv6-node--img, svg.cv6-node--img.replaced-svg, img.cv6-node--img { max-width: 48px !important; max-height: 48px !important; width: auto !important; height: auto !important; } }
I have a soluition in mind and will try to deploy a new version later this week.
