ReplaceTriggeredBy: Still not working in Golang

[eahrend]

Expected Behavior

I should be able to create a replaceTriggeredBy lifecycle rule by specifying the FQN of the resource that I want to cause a replacement trigger for, like:

    triggersMap := map[string]*string{
        "databases": jsii.String(strings.Join(dbNames, ",")), // trigger on database changes
    }
    resourceId := jsii.Sprintf("cloud-sql-user-%s-%s-%s-trigger", h.ProjectName, h.Struct.Name, userName)
    userReplacementTrigger := nr.NewResource(h.Stack, resourceId, &nr.ResourceConfig{Triggers: &triggersMap})
    lifecycle := cdktf.TerraformResourceLifecycle{
        ReplaceTriggeredBy: &[]interface{}{
            userReplacementTrigger.Fqn(),
        },
    }

Actual Behavior

I get an invalid expression. The cdktf.json file shows:

    "google_sql_user": {
        ###REDACTED###
        "lifecycle": {
          "replace_triggered_by": [
            "${null_resource.cloud-sql-user-my-instance-default-user-trigger}"
          ]
        },
        ###REDACTED###
      },

Steps to Reproduce

Apply the stack with the relevant code.

Workarounds

Workaround is to write it like this:

    lifecycle := cdktf.TerraformResourceLifecycle{
        ReplaceTriggeredBy: &[]interface{}{
            // Workaround for https://github.com/hashicorp/terraform-cdk/issues/3196
            fmt.Sprintf("%s.%s", *userReplacementTrigger.TerraformResourceType(), *userReplacementTrigger.FriendlyUniqueId()),
        },
    }

Anything Else?

I am interested in working on this issue.

I am also experiencing this issue with Python, have tried providing just the resource variable and using .fqn as 3322 code changes suggest.

The workaround by @eahrend seems to work

lifecycle=TerraformResourceLifecycle(
    replace_triggered_by=[
        f"{self.__redshift_namespace.terraform_resource_type}.{self.__redshift_namespace.friendly_unique_id}",
    ]
)

"lifecycle": {
      "replace_triggered_by": [
          "aws_redshiftserverless_namespace.redshift__redshift_namespace"
      ]
    },

I believe the underlying issue is that the fqn property includes the hcl templating syntax as shown below in the cdktf.json when I use fqn:

lifecycle=TerraformResourceLifecycle(
    replace_triggered_by=[
        f"{self.__redshift_namespace.fqn}",
    ]
)

"lifecycle": {
      "replace_triggered_by": [
          "${aws_redshiftserverless_namespace.redshift__redshift_namespace}"
      ]
    },

I am not sure if fqn including the syntax is by design, but that seems to be the underlying issue.

any progress on this?
