Error extracting the access token

[mahesh5]

Am using the example to integrate fitbit but am getting this error.
"There was an error extracting the access token from the authentication response." Do i need to encode clientID or clientSecret.

with
if let token = AuthenticationController.extractToken(notification, key: "fivedotsfitbit://#access_token") {
