Error retrieving droplet from resource bytes: %w

Error message

Error retrieving droplet from resource bytes: %w

What it means

Wraps fi.ResourceAsBytes failure in the DO droplet Terraform renderer while materializing the droplet's user-data resource into bytes for the terraform file store. Fires when the user-data resource cannot be read (e.g. bad template or reader failure).

Solutions

1. Check the user-data template for errors
2. Inspect the wrapped resource-read error
3. Regenerate Terraform output after fixing
