Can't use undefined value as ARRAY reference
Hi, When running the program I get an error
Can't use an undefined value as an ARRAY reference at lib/AWS/Network/SecurityGroupMap.pm line 154.
Hi,
Sorry for not seeing this before (It kind of got lost between other stuff). Since the error is here: https://github.com/pplu/aws-map/blob/master/lib/AWS/Network/SecurityGroupMap.pm#L154
It would look like you have an ELBv2 with no SecurityGroups. Can you do a DescribeLoadBalancers in the ELBv2 API (can be done with the AWS CLI) and send me the results? (please redact any identifying or delicate information).
This will probably be solved by adding a return if (not defined $elb->SecurityGroups) on line 153.
Can you try that and report if it worked?
Hello !
I've got the same error," Can't use an undefined value as an ARRAY reference at lib/AWS/Network/SecurityGroupMap.pm line 154"
I've added :
return if (not defined $elb->SecurityGroups) on the line 153 but then I have too many errors.
Can I have some help please ?
Thank's !

@Hindmalti : the way I had suggested the fix there was a syntax error (missing ;) at the end of the line. I've pushed to master correct code.
If you still get errors it could be because you're using a very old Perl (aws-map needs Perl > 5.18 https://github.com/pplu/aws-map/issues/7). You can use https://perlbrew.pl/ to get a modern Perl running, or take a look at running aws-map from a Docker container (you have a working Dockerfile in the project).
Please tell me if this helped.
