Can not parse file that has "in" attribute

[aston-r]

Hi,

STR:

• create the tf file with context:

  resource "aws_api_gateway_rest_api" "example" {
  
  body = jsonencode({
  security_definitions = {
      sigv4 = {
        type                         = "apiKey"
        name                         = "Authorization"
        in                           = "header"
        x-amazon-apigateway-authtype = "awsSigv4"
      }
    }
  })
  }

Actual Result:

Upon testing this in https://www.lark-parser.org/ide/ changing the parser to Earley seems to not have this error. Being mostly ignorant in this topic, is there any reason to use a specific parser?
