bcrypt Error: data and hash arguments required

Question

I am getting a bcrypt error stating that data and hash arguments are required, referencing line #44 in my routes.js file. From what I can tell, I am passing that information

Answer 1

bcrypt.compare takes 3 parameters; passwordToCheck, passwordHash, and a callback, respectively. (Check the documentation for examples)

This error means one or both of the first 2 parameters are either null or undefined. Therefore, make sure both of them are passed correctly. (Not as null or undefined)
