Example error?

[csullens-work]

Hi,

I'm very new to Terraform, and want to add my AWS Redshift to the mix. I'm trying to "plan" the very basic example and I'm hitting the error:

* module.redshift.output.this_redshift_cluster_vpc_security_group_ids: Resource 'aws_redshift_cluster.this' does not have attribute 'vpc_security_group_ids' for variable 'aws_redshift_cluster.this.vpc_security_group_ids'

Any ideas?

thanks,
Chris

Probably example has to be updated, pull-request is welcome.

I'm seeing the same error, and I'm not running one of the examples. I'm no expert, but the module source looks correct; I'm not sure why aws_redshift_cluster.this doesn't have a vpc_security_group_ids attribute.

[jaypatrickhoward]

Only happens when no value is supplied for vpc_security_group_ids. I edited main.tf and hard-coded a dummy value (["abc"]) and no longer get the error.

Think it may have to do with the count=0 behavior introduced in terraform 0.11:

I'm using 0.11.

@csullens-work Thanks for opening this issue. Apparently, an example was not in a good shape.

Indeed `vpc_security_group_ids` is required.

* module.redshift.aws_redshift_cluster.this: 1 error(s) occurred:

* aws_redshift_cluster.this: [WARN] Error modifying Redshift Cluster (my-cluster): InvalidParameterValue: The vpc-security-group-ids parameter must have at least one argument.

I have updated the code in 4ba92b6 , tested it and released v1.4.0.
