Was this fix released onto pic.js (@dfinity/pic)? I am getting the same error @rem.codes got there now too.
EDIT:
This is the error I’m getting with
"@dfinity/pic": "^0.13.1",
Any help is appreciated @mraszyk
SOLUTION:
I upgraded to dfx 0.26.0 (from 0.25.0), reinstalled my nns extension and followed the rest of the nns guide normally and it works now!
