Environment

ruby 2.5.1
rails 6.0.3.2
devise 4.7.2
mac catalina 10.15.5
https://localhost:9292/

If i press send me reset password from the devise forgot your password page

ArgumentError in Devise::Passwords#create
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true

And the err message appears.

So, register for sendgrid (English)
config>environments>development.rb
Add the following to

config.action_mailer.default_url_options = {host: ENV['SG_WEB_HOST'], protocol: ENV['SG_WEB_PROTOCOL']}
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :https
  config.action_mailer.https_settings = {
    :address =>ENV['SG_SMTP_ADDRESS'],
    :domain =>ENV['SG_DOMAIN'],
    :port =>ENV['SG_PORT'],
    :user_name =>ENV['SG_USER_NAME'],
    :password =>ENV['SENDGRID_API_KEY'],
    :authentication =>'login',
    :enable_starttls_auto =>true

Add the following to .zshrc
SENDGRID_API_KEY is private.
SG_SMTP_ADDRESS,SG_DOMAIN
Does not know what to write.

export SG_USER_NAME='apikkey'
export SENDGRID_API_KEY=''
export SG_WEB_HOST='api.sendgrid.com'
export SG_WEB_PROTOCOL='HTTPS'
export SG_SMTP_ADDRESS=''
export SG_DOMAIN=''
export SG_PORT='TCP 443'

I investigated and tried it for about 6 hours, but it did not solve it.
If anyone knows, we would appreciate it if you could answer.
Thanks for your cooperation.
