Adding After afterResponse error handing breaks authentication

I’ve added the following error handling to the middleware using the ‘afterResponse’ property. This seemed to work for the validation of the action responses but it breaks the authentication which dies with the error below. If I take the ‘afterResponse’ property out authentication works. What am I missing here?const handleErrors = (response, z) => {    // Prevent `throwForStatus` from throwing for a certain status.
if (response.status === 400) {
response.skipThrowForStatus = true;
throw new z.errors.Error(response.json.error.message, response.json.error.code, response.status);
} else if (response.status === 404) {
response.skipThrowForStatus = true;
throw new z.errors.Error(response.json.error.message, response.json.error.code, response.status);
}
};

authentication failed: Middleware should return an object. What happened (You are seeing this because you are an admin): Starting GET request to http://30dd3db01e47.ngrok.io/api/v2/integrations/zapier/me Received 200 code from http://30dd3db01e47.ngrok.io/api/v2/integrations/zapier/me after 982ms Received content "{"success":true,"message":"Successfully authenticated","data":{"account":{"name":"AccountancyManager" Middleware should return an object.

Issue resolved.

I was working off the example here https://platform.zapier.com/cli_docs/docs#using-http-middleware but the HandelErrors function requires a 

return response;

As the last line of the function. This is missing from the example but is present in the the sample project in GITHub.
