Sendgridにメールが送れない

Question

現在、Railsチュートリアルにて学習中の者です。
Sign in の時に、Sendgridにメールを送って認証したら、log inできるという機能を作っているのですが、Send gridの方にメールが届かないので、メール送信の処理に問題がないか試してみました。→　> heroku run rails console
すると、エラーが出ました。

session_controllerを確認しても、
エラーらしいエラーはありませんでした。

class SessionsController < ApplicationController

  # GET /login
  def new
    #@session = Session.new
  end

  # POST /login
  def create
    user = User.find_by(email: params[:session][:email])
    if user && user.authenticate(params[:session][:password])
      if user.activated?
        # Success
        log_in user
        params[:session][:remember_me] == '1' ? remember(user) : forget(user)
        redirect_back_or user
      else
        message  = "Account not activated. "
        message += "Check your email for the activation link."
        flash[:warning] = message
        redirect_to root_url
      end
    else
      # Failure
      flash.now[:danger] = 'Invalid email/password combination'
      render 'new'
    end
  end

  # DELETE /logout
  def destroy
    log_out if logged_in?
    redirect_to root_url
  end
end

問題があるのは他の部分でしょうか。

Answer 1

全角の空白が入っています。

ご回答ありがとうございます。
色々全角の余白がないかいじってみたのですが、
発見することができませんでした。
具体的にどこか教えていただけると嬉しいです。

あれ、読み違えたかな、
/app/app/controllers/sessions_controller.rb:7:in `<class:SessionsController>': undefined method `　' for SessionsController:Class (NoMethodError)
とありましたので、コピペされたソースでは良くわからなかったのですが、
sessions_controller.rb:7　7行目に
undefined method `　'　これ全角の空白　があると言ってるので
どこかに隠れているかな、と読んだのですが
7行目ってどこになりますか？

end　と # POST /login　の間？

[nana777]

そうです。
行間を系sたりもしましたが、上手くいきませんでした。

heroku run rails consoleをするといつもこのような流れになります。
ec2-user:~/environment/insta_app (chang-sending-email-function) $ heroku run rails console
bash: heroku: command not found
ec2-user:~/environment/insta_app (chang-sending-email-function) $ source <(curl -sL https://cdn.learnenough.com/heroku_install)

heroku/7.29.0 linux-x64 node-v11.14.0
ec2-user:~/environment/insta_app (chang-sending-email-function) $
これが原因でしょうか。

[winterboum]

herokuは使っていないのでheroku固有のことはわかりません
が
ec2-user:~　の .bashrc なり .bash_profile なりに heroku利用に必要な環境設定を行うようにしておくのが良いですね。heroku利用の手引に有るのでは？
で
それが原因である可能性は低いと感じます。

全角空白が無いことを確認した後も、同じ場所で同じエラーですか？
