I am having the exact same error message and I tried using different browsers including Tor and different addresses, all with same error results.
After checking your preview example I think that it should have some zoom option because I can't clearly see any address shown on your image.
Graphical transactions visualizer is a good idea but some explorer can show this and there are even some wallets like Sparrow who can do something similar with diagrams for transactions:
