IgUserProfile translation issue for name="error"

[Moon-sparkcentral]

Hi
We make a call for user profile with a sender id and we ask for name and profile_pic, the caller takes from GraphAPI gets this result :
{
"name": "error",
"profile_pic": "https://scontent-bru2-1.cdninstagram.com/v/t51.2885-15/s200x200/94007776_534488077252009_251463647916720128_n.jpg?_nc_cat=103&ccb=1-5&_nc_sid=8ae9d6&_nc_ohc=0SmYjQva3p8AX8Bt5IK&_nc_ht=scontent-bru2-1.cdninstagram.com&reslog=d&edm=ALmAK4EGAAAA&oh=870a850d69bbc1efe3b351016403d3df&oe=614D81A3",
"id": "6119198718152259"
}
but the result that we take is not that user profile, we get an exception with this message for it:

com.restfb.exception.FacebookGraphException: Received Facebook error response of type null: null (code 0, subcode null) 'null - null'

So you translate this profile wrong. Could you please look for it.

Can you please show the restfb calls you make to fetch the information and what mapping object you are using?

[Moon-sparkcentral]

this is our call
.fetchObject(senderId, UserProfile.class, with("fields", "name,profile_pic")));

The FacebookGraphException is something we receive from Facebook itself, so I suggest you enable logging on debug and check the generated URL. Maybe you can use curl or insomina (or something else) to check the validity.

Additionally, you can check the preconditions here: https://developers.facebook.com/docs/messenger-platform/identity/user-profile/

Do you meet them all before sending the request to FB?

I tried again with Curl and also on Facebook Graph Api UI and see the right data comes from FB GraphApi as I have mentioned in my first message. I have debugged it. So after the fetchObject() call , we get the exception.

[nbartels]

okay, so I have to build up a test environment for this.

Maybe you can check the general stuff in the meantime, user id correct, page access token used, network connection to Facebook okay...

[Moon-sparkcentral]

Yes I have checked all those stuffs, everything is ok.

To get this solved soon, I suggest you get in touch with us via email: team@restfb.com
So we can exchange sensitive data.

Okay, so we have analysed everything, and it is the username that runs in the program flow into the exception generator because it is "error". We have a short circuit that contains a string comparison and this is with this username very bad.

After understanding the problem, we will fix this with the next version.
