[sdk/go] RegisterResourceOutputs does not result in any outputs

What happened?

I created a component resource based on the docs on https://www.pulumi.com/docs/intro/concepts/resources/components/. I call ctx.RegisterResourceOutputs at the end to register some outputs. When running pulumi up no outputs are displayed and no outputs are available according to pulumi stack output.

Steps to reproduce

Create a component resource
Call ctx.RegisterResourceOutputs with pulumi.Map{} that contains key-value pairs
Run pulumi up

Expected Behavior

I expected the outputs I register to be shown at the end of pulumi up.

Actual Behavior

No outputs seem to exist and are not displayed on the console.
