I have noticed MJS error: failed to read file "app.js" on the console output when my esp8266 boots.
Is this because the system is expecting to see an app.js file in my fs folder?
app.js was introduced by https://github.com/mongoose-os-libs/mjs/commit/ce86d41dc6b5b071aef445459c3b1085d9447456
Have a look here
mos latest will not print an error if app.js doesn't exist: https://github.com/mongoose-os-libs/mjs/commit/98fa2df2a43270c89f62681b6ea813df2c63ae37
