Debug Output

Crash Output

Error: leftover module module.iam_user_test_user in state that should have been removed; this is a bug in Terraform and should be reported

Expected Behavior

The resource should have been removed once we have removed the user tf file.

Actual Behavior

Getting error

Steps to Reproduce

Initially using terraform 0.12.13 without any error. Download terraform 0.12.19 and set as default tf. terraform init terraform 0.12upgrade terraform validate generate test_user.tf file terraform init terraform plan terraform apply Remove test_user.tf file terraform plan terraform apply
