Updated successfully to 0.9.50
after updating everything works well (node 8.16, npm 6.4.1)
The update from version 0.9.48 to 0.9.50 worked fine (Node.js Ver 8.16).
Update (Stretch, node 10.15.3, npm 6.4.1) on Test-Pimatic worked without any issues.
Thanks!
Edit: Complete new installation also works.
Stretch

Re: pimatic@0.9.50
After the update I started receiving the following error:
error [pimatic-mobile-frontend]: Client error: TypeError: Unable to process binding "if: function (){return !$root.isGroupCollapsed($parent,$data) }"
Message: Unable to process binding "template: function (){return { name:$root.getItemTemplate,foreach:$parent.getDevicesInGroup($data.id),afterRender:$parent.afterRenderDevice} }"
Message: null is not an object (evaluating 'n[a]')
Anyone a clue on cause and solution?
Furthermore, my frontend is sometimes not responding on phone or tablet.
