• The regex string in replace() includes literal slashes and delimiters; Terraform expects a plain regex (e.g., "^(https?|wss?)://"), so adjust the pattern to correctly strip the protocol prefix.

tenzir_platform_domain_without_protocol = replace(var.tenzir_platform_domain, "/^(https?|wss?):\\/\\//", "")
