AWS images not working with CloudFormation

When attempting to use a new AWS image with CloudFormation (via Terraform) it fails with this error:

│ Error: error waiting for CloudFormation Stack creation: failed to create CloudFormation stack, rollback requested (ROLLBACK_COMPLETE): ["The following resource(s) failed to create: [devASGworkerA]. Rollback requested by user." "You must use a valid fully-formed launch template. The device 'xvda' is used in more than one block-device mapping (Service: AmazonAutoScaling; Status Code: 400; Error Code: ValidationError; Request ID: 49ca4896-1efa-467a-91a1-c07675b66448; Proxy: null)"]

Launching images on their own, however works. A quick search for similar error messages found this thread, similar problem experienced between Debian Jesse and Debian Stretch, the only difference is that the one that works specifies /dev/xvda instead of just xvda for block volume devices.

Fix is forthcoming
