Question

I am using bcryptjs library to encrypt password field but it is not able to encrypt and send to server.
The error that I’m getting is “localhost didn’t send any data” on my live server and
“/Users/vishnuvardhanvankayalapati/Desktop/A-Complete-Online-Shop/node_modules/bcryptjs/dist/bcrypt.js:214
nextTick(callback.bind(this, Error(“Illegal arguments: “+(typeof s)+’, ‘+(typeof salt))));
^

Error: Illegal arguments: undefined, number
