我是ruby的新手，我正在学习一个初学者教程，我创建了一个注册表单，但是提交按钮似乎没有正常工作。

注册控制器.rb：

class RegistrationController < ApplicationController
    def new
        @account=Account.new
    end

    def create
        @account=Account.new(params_account)
        if @account.save
           redirect_to root_path ,notice:"Successfully created account"
        else
            flash[:alert]="something went wrong"
            render :new
        end
    end

    def params_account
        params.require(:account).permit(:mail ,:passwor ,:password_confirmation)
    end
end

路由.rb：

Rails.application.routes.draw do
 
  get "about" ,to:"about#index"

  get "sign_up" , to:"registration#new"
  post "sign_up" , to: "registration#create"
  
  get "/", to: "main#index"
end

新的.html.erb文件：

<h1>Sign up</h1>
<%= form_with model: @account ,url:sign_up_path do |form| %>
<% if @account.errors.any? %>
 <div class="alert alert-danger">
    <% @account.errors.full_messages.each do |message|%>
       <div class="mb-4"><%= message %></div>
    <% end %>
</div>
<% end %>
<%= form.label :Email  %>
<div class="mb-4">
    
    <%= form.text_field :mail ,class:"form_control" ,placeholder:"rahma@gmail.com"%>
</div>
<%= form.label :Password  %>
<div class="mb-4">
    <%= form.password_field :password ,class:"form_control" ,placeholder:"password"%>
</div>
<%= form.label :Confirme_password  %>
<div class="mb-4">
    <%= form.password_field :password_confirmation ,class:"form_control" ,placeholder:"confirme your password"%>
</div>
<div class="mb-4">
    <%= form.submit "Sign up",class:"btn btn-primary"%>
</div>
<% end %>

我看了看终端后，我启动了服务器，它显示：

Started POST "/sign_up" for 127.0.0.1 at 2023-03-15 19:21:48 +0100
Processing by RegistrationController#create as TURBO_STREAM

而且没有错误，当我试图提交一些数据时，即使它们的格式很好，它也引发了一个错误：

我按照教程一步一步，一切为他工作，但不是我，我找不到问题在哪里.
