object is not subscriptable with instance_info['Tags'] #13
Hello - Alarm was not generated in my case as your python scripts ran into errors specially with instance_info:
instance_info = check_alarm_tag(instance_id, create_alarm_tag)
instance_info was returned either as bool or NoneType from check_alarm_tag, neither was considered subscriptable in process_alarm_tags(instance_id, instance_info, default_alarms, metric_dimensions_map, sns_topic_arn,
cw_namespace, create_default_alarms_flag, alarm_separator)
Below are the errors in Lambda log events (the line numbers may not be the same as in your scripts as I've added some print lines for debugging purpose):
[ERROR] TypeError: 'bool' object is not subscriptable
Traceback (most recent call last):
File "/var/task/cw_auto_alarms.py", line 149, in lambda_handler
process_alarm_tags(instance_id, instance_info, default_alarms, metric_dimensions_map, sns_topic_arn,
File "/var/task/actions.py", line 190, in process_alarm_tags
tags = instance_info['Tags']
'NoneType' object is not subscriptable: TypeError

tags = instance_info['Tags']
TypeError: 'NoneType' object is not subscriptable
I tried both Python 3.6 and 3.8. Why am I getting the above errors and how to resolve? Thanks!
