any.proto

```
import "google/protobuf/any.proto";

message Error {
  option deprecated = true;
  uint32 code = 1;                // Canonical gRPC error code.
  string message = 2;             // Human readable error.
  google.protobuf.Any data = 3;   // Optional additional information.
}
```
This fails when trying to build the generated code since any is a keyword in erlang.
