I tried to extend web_editor (in order to add custom font-size) last week but because i couldn't success, I undo everything and i continued to work on something else. There was no error but I now, when stop the docker and rerun again, i got this error below. If there is any idea how to solve it, I would appreciate that.  

Error:
