an object is created).
The `for_each` value must be a map or set with one element per desired
resource instance. When providing a set, you must use an expression that
explicitly returns a set value, like the [`toset`](/language/functions/toset)
function; to prevent unwanted surprises during conversion, the `for_each`
argument does not implicitly convert lists or tuples to sets.
The `for_each` value must be a map or set with one element per desired resource

does not implicitly convert lists or tuples to sets.
If you need to declare resource instances based on a nested
data structure or combinations of elements from multiple data structures you
can use Terraform expressions and functions to derive a suitable value.
