Prerequisites

• Search the existing issues.

Summary

When running dsc server and piping in parameters, the outer "parameters" wrapper is not supported. For instance:

parameters:
  message: Hello from the dscd parameters file!

is not supported. Only this is supported:

message: Hello from the dscd parameters file!

Both formats should be supported in the same way that the parameters file can be either format.
