"TypeError: Cannot read property 'push' of undefined" #13

Closed Vinisz closed 5 years ago

Vinisz commented 5 years ago

Describe the bug When pressing "Deploy" in node red, "TypeError: Cannot read property 'push' of undefined" appears for all the contrib-ui-level nodes in the debug window

To Reproduce Install new node-red system, install node-red-contrib-ui-level to the template, copy over the flow (via clipboard) from the old system, press "deploy" There are no issues with any of the other nodes, pallete items and flows on the new system

Expected behavior Normal Deploy, without the error, and the node showing up on the dashboard,

Screenshots If applicable, add screenshots to help explain your problem.

Environment and versions (please complete the following information):

Additional context Add any other context about the problem here . Dashboard has just released a new version, maybe this is where the problem lies... I did not use this version on the older system (Synology NAS) and did not have any problems there.

hotNipi commented 5 years ago

Did the previous installation ( from where you copied the flow) had same version of ui-level?

Vinisz commented 5 years ago

Yes, same level

hotNipi commented 5 years ago

Issue does not reproduce for me but as I don't have PI or similar environment available I cant really be sure what is wrong. I kindly ask you to do an experiment if you can. To isolate issue, can you do most simple flow, Inject and level node only and see if it has same issue. And in addition if possible can you please share the broken flow json or part of it?

Vinisz commented 5 years ago

Sure, no problem... I created the flow and published it, got the same error on the new condifigured node. Here is the flow :

For your informatiom, just did a fresh docker install of node-red (latest) on synology , installed dashboard and ui-level (both latest versions) , result : same error

hotNipi commented 5 years ago

What is the version of node.js you are using?

Vinisz commented 5 years ago

a "node --version" command inside the docker container reports: v 8.15.1 Hope that this is what you are looking for ? Oh, and on the raspberry PI it reports : v 10.15.3

hotNipi commented 5 years ago

Yep. Both should be fine. Digging deeper.

I ran into this this morning on a Pi and then tried the same thing on my Mac which had no problem. Then I noticed the Pi was back on NR v0.19.5 and the dashboard was old. I upgraded everything and the issue went away.
