request error with message=null and fieldname="n/a"

[luca_diba]

I am trying to build an app that uses Fitbit Web API. I was testing the OAuth 2.0 APIs and, at a certain point, step 1A stopped working. I thought that the problem was my app, so I went to the tutorial page and used curl requests (which I used befor and worked), receiving the same strange error.

The authorization URL (https://www.fitbit.com/oauth2/authorize?...) works. The redirection works, and I obtain a code, but when I try to make the next request:

curl -i -X POST \
 -H 'Authorization: Basic ****' \
 --data "clientId=****" \
 --data "grant_type=authorization_code" \
 --data "redirect_uri=****" \
 --data "code=****" \
 -H 'Content-Type: application/x-www-form-urlencoded' \
https://api.fitbit.com/oauth2/token

I obtain the following response:

{"errors":[{"errorType":"request","fieldName":"n/a","message":null}],"success":false}

 What could be the problem, given that I even used curl requests by copying and pasting them from the tutorial itself?

Hi @luca_diba 

Would you please try resetting your client secret and try again?

Thanks!
