Remove "Maintype was not text, image, or querystring" exception.

[Vikash B]

I am getting this error but the same code was working perfectly fine in march.

In [14]: posts = graph.get_connections('johnkasich', 'posts', limit=80, fields='likes.su
mmary(true),comments.summary(true),name,message,type,id,created_time,shares')

Are you using 1.0.0? What version were you using when the code was working?

[Vikash B]

I did a pip upgrade after it dint work today but that dint help. Right now I got 1.0.0 on pip freeze.

Irrespective of that, the same query is working on the Graph API Explorer: https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=johnkasich%2Fposts%3Ffields%3Dlikes.summary(true)%2Ccomments.summary(true)%2Cname%2Cmessage%2Ctype%2Cid%2Ccreated_time%2Cshares&version=v2.6

[Martey Dodoo]

I ran the get_connections code and pulled the response from Facebook:

{"error":{"code":1,"message":"Please reduce the amount of data you're asking for, then retry your request"}}

This isn't an issues with get_connections, but rather with the error handling code in the request method - the generic "Maintype was not text, image, or querystring" error message hides other exceptions and should be changed.

[Vikash B]

@martey is there any quick fix for this?

[Vikash B]

Worked when making limit to 25. earlier I used to get reduce amount of data error and making it earlier 80 worked.

[Martey Dodoo]

@martey is there any quick fix for this?

If you are referring to the fact that you might receive a generic error message, you could replace line 271 (that raises the generic error message) with return response.

What is left to do in this PR?

[MuffinFox]

The error handling of the lib is unfortunately still broken, can we agree on removing the generic error. It seems not to be possible to handle server errors like 50x

I see 2 main issues in the main requests method:

     except requests.HTTPError as e:
            response = json.loads(e.read())
            raise GraphAPIError(response)

Not sure when HTTPError will be raised because raise_for_status is not in use, but if i mock Http Errors, this wont work, obviously because AttributeError: 'HTTPError' object has no attribute 'read', also HTTPError.response is lost if it was working.

Further we need to get rid of this generic error, response context is lost:

raise GraphAPIError("Maintype was not text, image, or querystring")
