That’s an error in the original NuPACK code. NUPACK fails to fold certain sequences for some reason. We won’t be able to fix this since it’s not a problem in the Eterna system, it’s something flawed in the NuPACK algorithm we are borrowing.

Thank you for reporting the error message! Now everyone else will know as well. I’ve only gotten the error message once myself, while solving a player pseudoknot puzzle.
