Terraform:“解码JSON时出错:JSON:无法将字符串解组到Go struct field ContainerDefinition”aws\u ecs\u task\u definition resource

我从terraform文档中复制了这个资源块,并更新了值。但是,当我触发管道时,我的错误率低于,无法解决它。

我的版本: source=“hashicorp/aws” 版本=“~>3.0”

我的资源:

resource "aws_ecs_task_definition" "aws-ecs-task" {
  family                   = "${var.app_name}-task"
  network_mode             = "awsvpc"
  requires_compatibilities = ["FARGATE"]
  cpu                      = 256
  memory                   = 512
  execution_role_arn       = aws_iam_role.ecsTaskExecutionRole.arn
  task_role_arn            = aws_iam_role.ecsTaskExecutionRole.arn
  container_definitions = jsonencode([
    {
      name        = "${var.app_name}-${var.app_environment}-container"
      image       = "${var.repository_url}:latest"
      essential   = true
      environment = "${var.app_environment}"
      essential = true
      portMappings = [
        {
          containerPort = 8080
          hostPort      = 8080
        }
      ]
    }
  ])
  tags = {
    Name        = "${var.app_name}-ecs-td"
    Environment = var.app_environment
  }
}

我的错误输出:

Error: ECS Task Definition container_definitions is invalid: Error decoding JSON: json: cannot unmarshal string into Go struct field ContainerDefinition.Environment of type []*ecs.KeyValuePair
