Well, it's your assumption. No more no less. But what about the diagnostics instead of assumptions? WIll IPS provide informative error instead of just "-200"?
93 frames and 816kb is nothing for GIFs. Most of uploaded GIFs on my forums has a lot more frames and sizes (and a lot of them was uploaded when i used ImageMagic).

As i already said, problem is not related to the count of frames of to the size of the GIF, it just appears with some of GIFs, not matter how large or small they are, or how much frames does they have. I've uploaded bigger GIFs with much more frames and it worked just fine. Played around with timeouts and memory limits, e.t.c. and it does not affected the error with GIFs which has lower size and less frames.
Does not matter, the actual problem is lack of information in the error, that's it.

When you set up a custom confidential OAuth client, you can choose which scopes are available. Look at the "Scopes" tab.

 
By default, "profile" and "email" are the two valid scopes that are created, but you can adjust and make others.

The rawProperties array essentially lets you adapt any column in the core_members database table.

You POST to the /core/members/X endpoint and set rawProperties[pp_reputation_points] to whatever value you want.
