Drop-in: dwolla-business-vcr renders with "undefined"

I am working locally with drop-in components for business registration, specifically the <dwolla-business-vcr> component.

I have a problem, it initially renders with an “undefined” error message:

There is no indication, that I can see, as to why there is the “undefined” error message or what it relates to. The configuration is as follows:

	<script type="text/javascript">
		dwolla.configure({
			environment: "sandbox",
			tokenUrl: "/dwolla/token",
			success: (res) => console.log(JSON.stringify(res)),
			error: (err) => alert(err)
		});
	</script>

and

  		<dwolla-business-vcr
  			terms=”http://dev.whatever.com:9090/terms”
  			privacy=”http://dev.whatever.com:9090/privacy”>
  		</dwolla-business-vcr>

Even with the “undefined” message, the component seems to function mostly normal, until you get to the end of the multi-step process and the submission fails with a 401. But I guess I’m looking to solve the “undefined” problem first…

TLDR: Why does the <dwolla-business-vcr> drop-in component render with “undefined” at the top?
