Unable to parse comments in the list

[Alexander Charykov]

I've following code in my terraform:

locals {
  mymap = concat([{"1": "1"}],
  # comment
  [{"2": "2"}])
}

which is not able to load:

UnexpectedToken: Unexpected token Token('LSQB', '[') at line 4, column 3.
Expected one of:
	* RPAR
Previous tokens: [Token('_NEW_LINE_OR_COMMENT', '# comment\n')]

But it is correct terraform syntax.
