I cannot connect Mastodon AP

When I attempt to connect to //mastodon.social/oauth/authorize, I observe:

The requested scope is invalid, unknown, or malformed.

A Screencast That Demonstrates That Discourse Meta Fails To Connect To Mastodon.Social

I cannot upload a GIF, for a non-descript error appears

For meta.discourse.org/t/398803/1, I attempted to upload an image/GIF file. However, Discourse returns a non-descript error, despite the file being 15 FPS, and < 600 KiB: "response": { "status": 422, "statusText": "", "httpVersion": "HTTP/2", "content": { "mimeType": "application/json; charset=utf-8", "size": 63, "text": "{\"errors\":[\"Sorry, but your upload failed. Please try again.\"]}" }, "redirectURL": "", "headersSize": 438, "bodySize": 501 },

FYI @pmusaraj / @angus in case you have ideas.

A potential fix in FIX: Switch to `scopes` from `scope` for Mastodon verification by pmusaraj · Pull Request #297 · discourse/discourse-activity-pub · GitHub, but I need to report this upstream to Mastodon… not seeing if/when the spec changed here.

This should be fixed now here on meta.
