A JavaScript error occurred in the renderer process #61

Closed WhistleMaster closed 7 years ago

WhistleMaster commented 7 years ago

Got the following weird error "A JavaScript error occurred in the renderer process" which keeps coming again and again, which makes the IDE completely unusable...

Found this, maybe it can help: https://github.com/electron/electron/issues/2479

This error's coming from the mDNS library - it's unhappy with a packet that's been received from something on the network. Short of changing to a different zeroconf library, I'm not sure what we can do about this!

I understand but it makes Tide completely unusable as the error is popping continually...

Maybe the error could be catch and put in the log file ?

Sorry this is so frustrating @WhistleMaster, this dialog is being shown because of recent changes to exception handling. If you can get to the Javascript console (Window>Toggle Developer Tools), paste the following into a console and hit return.

window.onerror = null

That'll disable the messages for that document.

I don't want to resort to letting errors occur silently again as it gives a bad user experience when things fail - a failed save for example is a unhandled exception at the moment. This should be reported to the user. And buggy libraries that are raising exceptions should be fixed or replaced.

As far as I know, we can't catch errors from this library using Javascript's try/catch because the error happens in a callback - our code is not involved in the call stack. But if anyone knows of a way that would be a great fix for now.

I changed my mind - grab a copy of the latest beta once it's done building :) https://github.com/tingbot/tide-electron/releases/tag/v0.4.6-beta
