What is the issue?

When attempting to complete the Error Handling assignment, I receive this error:

_r_r is not defined

This error occurs on the return statement in .onError:

.onError(({ code, status }) => {
		if(code === "NOT_FOUND")
			return ""
	})

The error appears as soon as I type the "" after return.

Copying and pasting the tutorial-provided answer results in the same error.
