当我运行terraform plan时，我得到了以下错误:

当我在.terraform/modules/main.tf和variables.tf文件中修复它们时，计划是成功的，当我从CLI触发时，它通过了。但是，当我真正推送代码时当我从UI触发计划时它不起作用
所以，当我做terraform init --upgrade时。它恢复正常了，我可以看到同样的问题。
.terraform/modules/ec2-datapipeline/main.tf中的物质实际上是主要的。从名为"ec2- datap管线"的外部模块获取的Tf文件;在您自己的代码中引用(查找module "ec2-datapipeline")。
您必须修复"ec2- datap管线"的源代码中的错误，提交并标记它，然后在您自己的代码中更新源代码引用。
你的更改在重新初始化时消失的原因是，你通过了--upgrade开关，它告诉Terraform重新下载外部模块源，即使它们在.terraform/modules缓存中本地缓存。
