Terraform Version ``` terraform -v Terraform v0.12.10 + provider.aws v2.32.0 ``` ### Debug Output I masked some resource names and IDs. ``` terraform plan Refreshing Terraform state in-memory prior to plan...

Error: State format upgrade failed Error upgrading state file format from version 3 to version 4: failed to migrate primary generation of aws_lb.public_alb: invalid dependency reference "aws_subnet.1a-public": Attribute name required: Dot must be followed by attribute name.. ``` ### Expected Behavior ・terraform does not crash. ・terraform does not try to create ALB. ### Actual Behavior terraform tried to create ALB and it crashed ### Steps to Reproduce terraform 0.11.14 ``` terraform init terraform apply terraform 0.12checklist terraform state pull | perl -ne 'print $_ if /depends_on/ .. /\]/' | perl -ne 'print $_ if /\.[^a-z*]/i' | sort -u ``` terraform 0.12.10 ``` terraform 0.12upgrade fix some variables, codes for terraform 0.12.10 terraform plan ``` ### Additional Context I tried to upgrade terraform 0.12. After upgrading terraform, it tried to create ALB, and it crashed. There is no ALB in my terraform state list. How can I solve this problem? Thank you.
