Uncaught Subscriptions field (.K) not defined for observable child Error only when using knockout.debug about knockoutjs-reactor HOT 9 CLOSED

Weird. KO 3.4.0 removed the ko.DEBUG variable... so we need a new way to detect debug vs compiled version... it seems that ko.subscriptions is a function defined only in DEBUG versions, so we may "stick" to that.

Yes it looks fine now for me. Thanx

First, try reactor 1.3.8 because I added support for KO 3.4.1 in 1.3.8.
Second: it's weird that you get a "K" error on the DEBUG version of knockout: I guess you missed something.. please double check what version of knockout you are using... try running "ko.DEBUG" in console to see if you really have a debug version of knockout and try "ko.version" to see the loaded version.

I got the same error when disposing the subscription. Also only when using the debug version, but I'm using KO 3.4.0 and reactor 1.3.8.

what does ko.DEBUG in console says?
can you create a jsbin/jsfiddle to show the isssue?

from knockoutjs-reactor.

ko.DEBUG is undefined.
I'll try to, but it may take a while, at the moment I don't have much time.
My fix for now is to just not use the debug version.

Hi I "blindly released" 1.3.9 with a fix to support debug versions of KO 3.4.0 and 3.4.1, that seems to have removed the ko.DEBUG variable export.

Please let me know if this fix your issue.

Thank you for reporting and for the final feedback!

I got same error when using with knockout 3.4.2.
guess subscriptionsField change to F.

     var subscriptionsField;
    switch (typeof ko.subscription == 'function' || ko.version) {
    case true: subscriptionsField = '_subscriptions'; break;
    case '3.0.0': subscriptionsField = 'F'; break;
    case '3.1.0': subscriptionsField = 'H'; break;
    case '3.2.0': subscriptionsField = 'M'; break;
    case '3.3.0': subscriptionsField = 'G'; break;
    case '3.4.0': subscriptionsField = 'K'; break;
    case '3.4.1': subscriptionsField = 'K'; break;
-   case '3.4.2': subscriptionsField = 'K'; break;
+  case '3.4.2': subscriptionsField = 'F'; break;
    default: throw 'Unsupported Knockout version. Only v3.0.0 to v3.4.2 are supported when minified. Current version is ' + ko.version;

After correcting as described above it worked properly
