publishEvent works in particle-api-js 8.0.0 but not in 8.0.1

I’m upgrading my Alexa Smarthome skill from using particle-api-js 6.4.3. I’m getting an exception calling particle.publishEvent when I upgrade to 8.0.1 or newer.

Running this code with particle-api-js 8.0.0 works without errors or exceptions.

function publish(name, data, token) {
    helper.log("publish name",name);
    helper.log("publish data",data);
    helper.log("publish token",token);
    let args = { name: name, data: data, auth: token }; // New version?
    helper.log("publish args",args);
    try {   // This shouldn't be necessary
        return particle.publishEvent(args).then(function(response){
            helper.log("publish response",response);
            let result = response.body.ok;
            return result;
        }, function (err) {
            helper.log("publish error",err);
        });
    } catch(error) {
        helper.log("publishEvent exception", error);
    }
}

On 8.0.1 or newer, I see the “publishEvent exception {}” log.
Also, in the CloudWatch logs I see this shortly after the above message:

        "    at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
    ]
}

I’m not sure what to do now, besides just staying at v8.0.0. Any suggestions how to proceed or debug further?

Hi @ronlisle - thanks for reporting this issue. It looks like a bug to me, but I’d like to dig in a little deeper. Would you mind opening a support ticket (support.particle.io) with a bit more information (describing the entire flow)? We’ll update this thread once we have come to a conclusion!
