Get an Exception - Cannot read property 'find' of undefined

[sunkay]

Here is my mongol config... I dont know why it is getting undefined.

if (Meteor.isClient) {
Session.set("Mongol", {
'collections': ['Posts'],
'display': true,
'opacity_normal': ".7",
'opacity_expand': ".9",
'disable_warning': "false"
});
}

1.0.2 March 13th, 2015 installed

Hi @sunkay @msavin. I'm having the same problem. It used to work until I ran meteor update last night. I can't get it to work despite attempts to downgrade versions by manually editing .meteor/versions file.

Exception from Tracker recompute function: Cannot read property 'find' of undefined
TypeError: Cannot read property 'find' of undefined

Upon checking my git changes in versions file, there were various modified/added related to mongol. I can't tell where the problem on dependencies/dependants package is.

+babrahams:editable-json@0.3.9
-dburles:mongo-collection-instances@0.3.1
+dburles:mongo-collection-instances@0.3.3
+gwendall:session-json@0.1.7
+lai:collection-extensions@0.1.3
-msavin:mongol@0.6.5
+msavin:mongol@1.0.2

Is there anyway I can downgrade to mongol 0.6.5 to test?

Thanks!

Hi @sunkay @msavin. Finally! Got it working after being pointed to COMPATIBILITY.md while reading Additional Information section on the README.md. :)

// be sure to use collection names, not variables

I didn't notice it immediately since I headed straight to CHANGELOG.md after noticing git changes on mongol version. Wew!

perfect @arvi.. that's it. Thanks.
