 Couple of notes to address:
 1. You need to generate a function named check_trigger_criterion(args), where input is a json object. The example of this json object is {{args_example}}.
-2. The input to this function comes from the arguments. You must use "ArgumentParser" to take an argument named "states", and then use "parse_known_args" to get the raw args.
+2. The input to this function comes from the arguments. You must use "ArgumentParser" to take an argument named "trigger_args", and then use "parse_known_args" to get the raw args.
 3. After getting the raw args, you need to use 'clean_args = bytes(raw_args, "utf-8").decode("unicode_escape")' to clean the raw argument, and then use 'args = json.loads(clean_args)' to get the json args.
 4. Based on the user's request and input args, generate the function logic and ONLY return a boolean value.
 5. You must only call check_trigger_criterion with the parsed json args in "if __name__ == '__main__'" block, and print only the function output. If any error occurs, print "Error".
