解決

こちらを参考にconfig/environments/development.rbとconfig/webpacker.ymlを編集して解決しました

Last configuration for Yarn and Webpacker

Rails does a lot of checkups on Yarn, a bit too much. Best is to disable this:
# config/environments/development.rb
config.webpacker.check_yarn_integrity = false
Also, we need to tell Rails that the webpacker server is running on the host webpacker and enable hot module reload. So set these values:
# config/webpacker.yml
development:
  dev_server:
    host: webpacker
    hmr: true
