问题
While working on my bot through Microsoft Azure's "Bot Sevice" template, I clicked "save" on a change to index.js, and received an error "Unable to save," but then the entire file went blank, and I lost all the code for my bot - which was already live! It is deployed through Bot Framework to places like Slack, Kik, Facebook and others...
Is there a way to recover this file? The only version I have backed up locally is too old to be much use.
Thanks!
