OAUTH issue. Error: Permission denied to access property "Package"


I am experienced programmer and I have been learning Meteor. I have run through the basic tutorials a couple of times. A few months back I set up the basic todo app and installed the FB/GitHub etc auth packages, set up the secrets and no problem. All worked well. Away I went on learning more Meteor.

This time … not so good. I get the error in the topic line. “Error: Permission denied to access property “Package””

I have googled, poked around the forums and elsewhere. Any help would be appreciated.


Further clarification : I am using the popup login and the login through FB or Github seems to go just fine. The error is generated in end_of_popup_response.js line 18 which is

if (window.opener && window.opener.Package &&

Sorry for my lack of clarity. I can supply any other details and appreciate any assistance.


Maybe digging a big hole in my yard helped. :slight_smile:

I chased this for several days. Used several browsers Downloaded another browser today - and the error message changed slightly in the new browser.

Uncaught SecurityError: Blocked a frame with origin “http://localhost:3000” from accessing a frame with origin “”. Protocols, domains, and ports must match.


My apologies to all for a time wasting post.


Now to figure out how to mark it solved…
