HCL parses fails on Maps when a value of a key is an expression

[wzur-r3]

I have a following code:

resource "aws_iam_role" "jenkins_orchestrator" {
  name_prefix = "jenkins-orchestrator"
  assume_role_policy = jsonencode({
    Version = "2012-10-17"
    Statement = [
      {
        Sid    = ""
        Effect = "Allow"
        Principal = {
          Federated = data.aws_iam_openid_connect_provider.cluster.arn
        }
        Action = "sts:AssumeRoleWithWebIdentity"
        Condition = {
          StringEquals = {
            "${replace(data.aws_iam_openid_connect_provider.cluster.arn, "arn:aws:iam::${data.aws_caller_identity.current.account_id}:oidc-provider/", "")}:sub" = "system:serviceaccount:${var.kubernetes_namespace}:${var.helm_release_name}"
          }
        }
      }
    ]
  })

  tags = var.tags
}

HCL4J fails to parse the map passed to StringEquals. The value of the key in that map has to be calculated, so it cannot be a constant.

HCL4J complains the ) character was unexpected, which was the one in oidc-provider/", "")}:sub

I noticed the same somewhere else, when I tried to create a map with a common prefix for the keys:

locals {
   mapExample = {
      "${var.prefix}-suffix-1": "value1",
      "${var.prefix}-suffix-2": "value1",
      "${var.prefix}-suffix-3": "value1",
  }
}

but I was able to refactor that to something HCL4J could consume.

HCL has following syntax for the keys in maps:

• id - which is a string of value of id
• (some-function()) - which allows to use a function and it has to be surrounded by () to distinguish it from the first case
• "some-string-possible-with-${interpolation}" - which is what I have in examples above
