Hello, I had problems setting up Augury.

I got this error message when opened google's chrome. TypeError: Cannot read property 'subscribe' of undefined at chrome-extension://elgalmkoelokbchhkhacckoklkejnhcd/build/backend.js:31:261926 at M (chrome-extension://elgalmkoelokbchhkhacckoklkejnhcd/build/backend.js:31:260124) at chrome-extension://elgalmkoelokbchhkhacckoklkejnhcd/build/backend.js:31:261814 at ZoneDelegate.invoke (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:242:26) at Zone.run (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:113:43) at eval (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:520:57) at ZoneDelegate.invokeTask (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:275:35) at Zone.runTask (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:151:47) at drainMicroTaskQueue (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:418:35) at ZoneTask.invoke (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:349:25) at data.args.<computed> (eval at <anonymous> (http://localhost:8080/polyfills.f9e0449db21613fa8768.js:2162:2), <anonymous>:1224:25)
