Terraspace integration with localstack

I am integrating terraspace with localstack, but getting below errors. I have mentioned main.tf and error. Can someone please suggest on it.

Localstack docker : docker run --rm -p 4566:4566 localstack/localstack

Haven’t played with localstack yet so unsure :face_with_monocle:

Looked into the stack trace though. So terraspace up basic calls terraspace build internally. In the stack trace it looks like at terraspace-2.0.2/lib/terraspace/cli/up.rb:9 which leads to

Unsure exactly why the stack trace does not show the lead-up to the layering.rb:6. But traced it anyway and basically, it is the result of calling @mod.cache_dir in builder.rb

The @mod.cache can actually be configured with a config setting. The default is ":REGION/:APP/:ROLE/:ENV/:BUILD_DIR" Docs:

https://terraspace.cloud/docs/config/reference/

So the :REGION is a cloud plugin-specific value, which is why it’s calling out to the AWS API and trying to get the value.

As a test, maybe try overriding the setting without :REGION:

config/app.rb

Terraspace.configure do |config|
  config.build.cache_dir	= ":APP/:ROLE/:ENV/:BUILD_DIR" # without :REGION
end

That might work. Unsure if other AWS API calls might still occur, though.
