所以，我从3.0到4.0，上周升级了Rails应用程序，并从那时起我已经得到，似乎指向我并没有改变随机的地方奇怪的错误，我不能复制它们。
一个这样的错误是这样的：
NoMethodError: undefined method `global_endpoint?' for AWS::S3:Class
[GEM_ROOT]/gems/aws-sdk-1.46.0/lib/aws/core/configuration.rb:441
/gems/aws-sdk-1.46.0/lib/aws/core/configuration.rb:441 in "block in add_service"
/gems/aws-sdk-1.46.0/lib/aws/core/configuration.rb:361 in "call"

/gems/paperclip-4.1.1/lib/paperclip/storage/s3.rb:247 in "s3_object"
/app/models/my_model.rb:49 in "block in my_download_url"
这将具有与保存在S3回形针附件的模型在页面上随机出现。 重新加载页面有时会再次导致它，但它通常会重新正确地装入无事。
我不知道该怎么调试它是什么，因为我甚至不能让它随意发生。
任何帮助或想法？
