Use POST to sign in. GET is not supported.

[Neithenn]

Not sure if is a devise-token-auth issue but anyway I would like to post it just in case that someone else happens the same.

After I installed devise-tokenauth and ng-token-auth I tried authentication via facebook leading to this error:

{"errors":["Use POST /sign_in to sign in. GET is not supported."]}

my rails logs:

Started GET "/omniauth/facebook/callback?code=AQCJG_Oz26o9PADnpL_arsnTN5E38EFikWZDXiQHXEYki1wPNt4dkqpXHE_8SrbGbweh29VmGQleegapuvVf8jOQmVhtz1prLy7GLRr40i07O24M4iNY8WQFVqKD3TIRmqgsj-puaP61KzUdpR0LHw_yeeguX38FDV_4KjHAHa0D4OLipA6ofd78eXQoEhvdkvtFnguuJGfKt0N6eEj9m1h185F2jkZqaZAwh6lM_VQTnDiwOWy10IHYA62yXWk0MJv28AhhoszC-R7tdFvxAEwn6C7IsMhxY7aBZp6VJwegJyQBBydwXb5QpMnOi4oNLSvi6oKARQkQ5i8Mku5tcqTA&state=8bf6fcfb4dedcf2f22fa3bef875d0e91b63ac0c9b7a8f8a6" for ::1 at 2017-01-29 12:38:34 -0300

Can't understand what's going on. Should my client start a Post method instead of get? is an issue of ng-token-auth?

I've seen another similar issue but was about CSFR.

I think the correct route is '/omniauth/facebook?code=4554564.....'
I got the same error with google gem

Possible workaround posted. Closing for now
