Uncaught RangeError: Trying to access beyond buffer length #317

Open KyleMaas opened 3 years ago

Error during sync, after previously refreshing the page mid-sync:

Tried refreshing the page again. Same error.

And I just got this alert() box:

An exception was encountered trying to read the messages database. Please report this so we can try to fix it: RangeError: Trying to access beyond buffer length

Yep, that seems to have just completely broken that instance. Can't load the Public tab anymore. It just sits there with the loading indicator up and never goes anywhere.

@arj03 Is there anything in that instance you'd need to figure out what's going on, or is it safe to clear that one out and rebuild it?

arj03 commented 3 years ago

oh that is pretty bad. I'll try and see if I can reproduce, sadly we don't have the option of extracting the db.

I'll note that I still get EBT debugging messages logged to the console (I have that enabled). So that's at least still trying to operate. But I can't access any messages.

Are we in a spot where I can wipe this instance or should I keep it around yet?

arj03 commented 3 years ago

Wiping is fine
