import ( "github.com/juju/juju/apiserver/params" ) // Create an error result with a message and code result := params.ErrorResults{ Params: []params.OneError{ { Message: "This is an error message", Code: "ERROR_CODE", }, }, } // Access the first error result message errorMessage := result.Params[0].MessageIn this example, we create an error result with a single error message and error code using the `ErrorResults` and `OneError` types provided by the package. We then access the error message through the result object. Overall, this package provides functionality for constructing and handling error results in the Juju API server.
