Error in response to storage.get

[er1x]

I can't get it to work (using Chrome Canary/Stable under macos). Got it working sometimes after some page refreshes, but seems random.

Popping development console it shows this:

Error in response to storage.get: TypeError: Cannot read property 'reduce' of null at drawTree (chrome-extension://jpigngmphmclcmikmcbcfplgnhlnefbp/app/assets/js/devtools.js:371:31) at Object.callback (chrome-extension://jpigngmphmclcmikmcbcfplgnhlnefbp/app/assets/js/devtools.js:287:33) at chrome-extension://jpigngmphmclcmikmcbcfplgnhlnefbp/app/assets/js/devtools.js:286:50
