Hello,

I just upgraded Z-way on my Razberry from 3.0.6 to 3.1.4. I use OpenRemote and therefore use OpenRemoteHelpers. However, OpenRemoteHelper call is getting:

Code: Select all

Uncaught TypeError: Cannot set property 'Access-Control-Allow-Origin' of undefined

as a response.

In z-way-server.log, there are many of these:

Code: Select all

Z-way will take action on the calls, but since the return is always the error, I can not get status updates.

Any idea what is causing this?

Thanks!

Make sure all files were updated properly. In your case in /opt/z-way-server/automation/Webserver.js on line 102 there should be:
if (!ret.headers) ret.headers = {};

Try to add just after this line and check the log:
console.logJS(ret);
