What does error: 'Object.keys(this._keyBindings)' mean?

HI

today I installed the mobile_app, and though it is not referenced in the error, this is flooding the log enormously:

2019-05-10 16:26:32 ERROR (MainThread) [frontend.js.latest.201904270] https://mydomain.duckdns.org:8123/frontend_latest/app.7bd99ba1.js?__WB_REVISION__=7bd99ba128ed85e3303e:2:60395 TypeError: undefined is not an object (evaluating 'Object.keys(this._keyBindings)')

I installed the config option, because I am testing the new beta 2.0 iOS app.

Would this be related?

thanks for having a look

Hello, same issue but not using IOS… I just installed Doorbird in HA (not sure it is related neither), mainly using a PC and a Android phone for accessing the frontend… I tried to look at the tokens around the time the problem occured (and the token where all blanks… I reloaded the page and eveything was fine)… If anyone can help us investigate what’s wrong … Thanks
