Hey this looks like a bug in the Cashu.me that I want to understand. Can you send me a DM? Let's figure out what went wrong!

I also tried a mint-to-mint transfer and got the same issue
This you do a mint to mint just right before this error? What was the last thing you did before?
I'm afraid some of your tokens might be borked, you might have to wipe your wallet. Hope you used only minimal amounts and it's your own mint, that would make it a lot easier to recover borked funds.
This is error pop up when you did the mint to mint? If so, that might be the issue.
