Ruby Rails Active Storage Exception - ruby-on-rails

Question

I'm working on a project in Ruby on Rails that I just added Active Storage to. Its throwing an exception and I can't quite figure it out. The aim is simply to allow a new registering user to upload an avatar image. In this case called :avatar_pic
Ruby 2.6.5
Rails 5.2.4
The error:
ActiveSupport::MessageEncryptor::InvalidMessage in UsersController#create

My Model:
class User < ApplicationRecord
attr_accessor :password
validates_confirmation_of :password
validates :email, :presence => true, :uniqueness => true
before_save :encrypt_password
has_one_attached :avatar_pic
def encrypt_password
self.password_salt = BCrypt::Engine.generate_salt
self.password_hash = BCrypt::Engine.hash_secret(password,password_salt)
end
def self.authenticate(email, password)
user = User.find_by "email = ?", email
if user && user.password_hash == BCrypt::Engine.hash_secret(password, user.password_salt)
user
else
nil
end
end
end
My controller:
class UsersController < ApplicationController
def new
#user = User.new
end
def create
#user = User.new(user_params)
#user.avatar_pic.attach(params[:user][:avatar_pic])
if #user.save
flash[:notice] = "You've successfully signed up!"
session[:user_id] = #user.id
redirect_to "/"
else
flash[:alert] = "There was a problem signing up."
redirect_to '/signup'
end
end
private
def user_params
params.require(:user).permit(:email, :password, :password_confirmation, :admin, :avatar_pic)
end
end
My view form:
<%= form_for #user do |f| %>
<%= f.label "Email" %>
<%= f.text_field :email, id: 'registration_email' %>
<%= f.label "Password" %>
<%= f.password_field :password, id: 'registration_password' %>
<%= f.label "Password confirmation" %>
<%= f.password_field :password_confirmation, id: 'reg_password_confirm' %>
<br>
<%= f.label "Upload Avatar Image" %>
<%= f.file_field :avatar_pic %>
<br>
<%= f.label "Admin?", name: 'admin_check', id: 'admin_check' %>
<%= f.check_box:admin %>
<br>
<%= f.submit "Sign Up" %>
<% end %>
So it seems the image uploads alright. I think my controller params are the problem and it isn't validating.... something. But I don't see how. I think it's in the params. I'm stumped.

Answer 1

Ok, so I found the problem. I had copied this repo down and it was originally developed on a different system. I didn't have the master.key (which I wasn't aware existed at the time).

I followed the instructions of Vladimir-19 and that solved it.
