How to get rid of console errors

David_K_6 — Wed, 16 Dec 2015 10:50:20 GMT

I regularly receive the following error in my app:

Uncaught TypeError: Cannot read property 'call' of undefined target-script-min.js:1283

This seems to be benign, but it would be nice to get rid of it, Any ideas?

It goes away if I remove the weinre script, of course.

(Apologies if anyone saw the earlier version of this post, which had some spurious stuff on it)

I assume you are not keeping the weinre script in your app when you publish it? That's not a good idea, it should be removed from your app before you publish your app.

Are you getting this when using the Emulate tab? If so, it can be ignored.

I've been sane enough to

I've been sane enough to remove it from most of the beta test builds (although I have been forgetting some, which is embarrassing).

I do have a zero-tolerance approach to console errors, though, so I don't really like the idea of "just ignoring it". So I guess that since I don't use the weinre debugger often (I either debug on the emulator, or use trace statements on a real machine), I'll just leave the script out most of the time unless needed.

Having said which, it wouldn't be a difficult thing for your developers to fix: all it needs is to make the following change to line 1283, from

return xhr.httpSocketHandler.call(xhr.httpSocket, xhr);

if (xhr.hasOwnProperty('httpSocketHandler')) {
    return xhr.httpSocketHandler.call(xhr.httpSocket, xhr);
}

If you can alert developers of this, that would be nice...
