Fixes #1423.
In REST streaming use case,
callback
is not provided. Instead, the caller expects to seeerror
events in the returned stream. If, for whatever reason, an error occurs in the streaming call, the caller would getTypeError: callback is not a function
.Make sure we only call
callback
if it's provided, and use the stream emitter to report errors in other cases.Note: the unrelated change to
mkdirp
import is just because they are apparently making ESM related changes. It just makes our code compile again.
