Historically helper/schema did not support non-primitive map attributes because they cannot be represented unambiguously in flatmap. When we initially implemented CoreConfigSchema here we mapped that situation to a nested block of mode NestingMap, even though that'd never worked until now, assuming that it'd be harmless because providers wouldn't be using it. It turns out that some providers are, in fact, incorrectly populating a TypeMap schema with Elem: &schema.Resource, apparently under the false assumption that it would constrain the keys allowed in the map. In practice, helper/schema has just been ignoring this and treating such attributes as map of string. (#20076) In order to preserve the behavior of these existing incorrectly-specified attribute definitions, here we mimic the helper/schema behavior by presenting as an attribute of type map(string). These attributes have also been shown in some documentation as nested blocks (with no equals sign), so that'll need to be fixed in user configurations as they upgrade to Terraform 0.12. However, the existing upgrade tool rules will take care of that as a natural consequence of the name being indicated as an attribute in the schema, rather than as a block type. This fixes #20076. |

Terraform Helper Lib: schema
The schema package provides a high-level interface for writing resource
providers for Terraform.
If you're writing a resource provider, we recommend you use this package.
The interface exposed by this package is much friendlier than trying to write to the Terraform API directly. The core Terraform API is low-level and built for maximum flexibility and control, whereas this library is built as a framework around that to more easily write common providers.
