I have a collection of facebook functions that relies on the httr package.
The usual procedure is that one has to set oauth app specs and facebook endpoints. Until recently this worked like a charm but now when I try to get the token by the oauth2.0_token function I get the error:
Waiting for authentication in browser... Press Esc/Ctrl + C to abort Authentication complete. Fejl i init_oauth2.0(self$endpoint, self$app, scope = self$params$scope, : Bad Request (HTTP 400).
You see my code below:
facebook_app <- oauth_app("facebook", key = "XXXX", secret = "YYYY")
# end point
facebook_ep <- oauth_endpoint(
authorize = "https://www.facebook.com/dialog/oauth",
access = "https://graph.facebook.com/oauth/access_token")
# token from endpoint and oauth
fb.token <- oauth2.0_token(facebook_ep, facebook_app, user_params = facebook_ep)
I have been to various posts and forums but I have not had luck in finding a solution yet.
Solved by settting:
Sys.setenv("HTTR_SERVER_PORT" = "1410/")
