social.exceptions.AuthStateMissing

Exception: social.exceptions.AuthStateMissing

This appears to be a duplicate of issue #166
I have followed the guidelines in the above issue but SESSION_PROTECTION was set to basic by default. Have played around with it being basic and strong - results are consistently the following traceback.

From further investigation with how Google Chrome handles cookies.
Adjusted my local domain name and authorization works without qualms.

Closing.

@jjshabs, could you, please, write more details about the solving of the problem? I've having the same issue and have no idea what to do :)

[phniix]

This should be a pretty quick fix for you @Uznick
What you want to do is use a legitimate domain and TLD for use inside of Chrome. Don't use the reserved localhost, or a TLD like .dev or .local.
For example, use:
foo.com
don't use:
foo.dev
foo.local
localhost
Make adjustments to your local hosts file and you will see that this works a treat =D

Thanks :)
