Parsing issue with nested splat operators

[Josh Barker]

Hi,

I've found an issue when parsing the below.

main.tf

variable "something" {
  description = "some object variable"

  type = list(object({
    id = string
    nested = list(object({
      id = string
    }))
  }))
  default = []

  validation {
    condition     = !contains([for v in flatten(var.something[*].nested[*].id) : can(regex("^blah-$", v))], false)
    error_message = "The property `nested.id` must be start with blah-."
  }
}

main.py

import hcl2
with open('main.tf', 'r') as file:
    dict = hcl2.load(file)

print(dict)

python main.py
Traceback (most recent call last):
  File "/Users/josh/.local/share/virtualenvs/empty-locals-s2Z1l-Fh/lib/python3.9/site-packages/lark/parsers/lalr_parser.py", line 59, in get_action
    return states[state][token.type]
KeyError: 'STAR'

During handling of the above exception, another exception occurred:
