- Missing resource instance key: Because aws_instance.count has "count" set, its attributes must be accessed on specific instances.
For example, to correlate with indices of a referring resource, use:
aws_instance.count[count.index]
- Unsupported attribute: This object has no argument, nested block, or exported attribute named "foo".`,
