Warning: Quoted references are deprecated

│ Warning: Quoted references are deprecated

│   on .terraform/modules/path/to/elbv2.tf line 226, in resource "aws_lb_target_group" "this":
│  226:   depends_on = ["aws_lb.this"]
│
│ In this context, references are expected literally rather than in quotes. Terraform 0.11 and earlier required

Solution: remove quotes. Use depends_on = [aws_lb.this] instead of depends_on = ["aws_lb.this"]
