subnet_ids expect string but is list

[esbenp]

I get the following error when creating a web-service module.

Error configuring: 1 error(s) occurred:

* variable subnet_ids in module browser_client should be type string, got list

Go the configuration from pingdummy. Unsure if this is a Stack issue or pingdummy but I thought I would report it regardless. Changed my config to join by , which seemed to fix the issue.

subnet_ids       = "${join(",",module.stack.external_subnets)}"

This is the expected way of doing it, there hasn't been work done on porting to terraform 0.7+ to support passing lists as variables.

@achille-roussel We need to use terraform lower then v0.7 ? I saw this https://github.com/segmentio/stack/blob/master/circle.yml#L4
I am getting a same problem as @esbenp , fixed with join
