Expected Behavior
terraform apply should run successfully.
Actual Behavior
terraform apply generates the following error:
│ Error: Invalid List Element Type
│
│ with example_resource.example,
│ on resource.tf line 9, in resource "example_resource" "example":
│ 9: resource "example_resource" "example" {
│
│ While creating a List value, an invalid element was detected. A List must use the single, given element type. This is always an issue with the provider and should be reported to the provider developers.
│
│ List Element Type: CustomObjectType
│ List Index (0) Element Type: types.ObjectType["int64_attribute":basetypes.Int64Type]Steps to Reproduce
