I'm trying to fetch some data from the [Stack Exchange API][1]
I have a valid `access_token` and registered key but I keep getting internal error as a result.
Here is the request URL:

    https://api.stackexchange.com/2.2/me?site=stackoverflow&access_token=Vy*iWEzkfPKHAzx7PEtJcA%2529%2529&filter=default&order=desc&sort=reputation&key=YKCpxEolLytlJiKBUCxUJg((

And the response:

    {"error_id":500,"error_message":"this error has been logged","error_name":"internal_error"}

What am I doing wrong/missing?

PS: I'm working on and an Android app and doing request with retrofit.
