Since you are using the ESP32, which goes through the console, this may be related to #289.

Ok, now that that's done, I tried it again on beta. It seems to be failing with reading the file. After some investigating, I notice (even testing locally) that it works fine with my local copy of circuitpython-repl-js, but not when using the published one despite it being up to date.

Blowing away my node_modules folder and reinstalling seems to have fixed it.
