Still works for me, both follow and unfollow. However it takes a while (maybe 1-2 minutes) specifically for Following Live Channels to update. Changes are immediately visible in Followed Channels though and you can also verify on the Twitch website that the follow/unfollow takes place immediately.

Further debug and i found this in the logs

DEBUG <general>: script.module.python.twitch: POST QUERY: url: |https://gql.twitch.tv/gql|, params: |{}|, data: |[{'operationName': 'FollowButton_FollowUser', 'variables': {'input': {'disableNotifications': False, 'targetID': '104833324'}}, 'extensions': {'persistedQuery': {'version': 1, 'sha256Hash': '14319edb840c1dfce880dc64fa28a1f4eb69d821901e9e96eb9610d2e52b54f2'}}}]|, headers: |{'Client-ID': 'kimne78kx3ncx6brgo4mv6wki5h1ko', 'Authorization': ''}|, target_func: |_follow_channel|

Looks like the call to gql functions is expecting some sort of authentication token which i appear to be missing.

This is the twitch plugin settings file (oauth keys redacted as XXX)

do i need to set the private_oauth_token and if so how?

[apo86]

Ah, yes that would be it. You do need the private token as well: https://github.com/anxdpanic/plugin.video.twitch/wiki/Private-API-Credentials---OAuth-Token

[deaddrop9]

Thanks for the reply, will try that later today.

For others benefit would it be better if the toggle followers button was disabled/hidden or at least checked the private oauth token was set and alerted user to how to enable it rather than the current process where it presents that it succeeded in following but fails in the background?

[apo86]

Yeah I agree. The GQL API responses look completely different than the regular API responses and there is no custom error handling set up. I played around a bit and it appears that the HTTP response code is always 200 OK, even for errors and the response body looks something like this:

[ { "data": { "unfollowUser": null }, "errors": [ { "message": "unauthenticated", "path": [ "unfollowUser" ] } ], "extensions": { "durationMilliseconds": 3, "operationName": "FollowButton_UnfollowUser", "requestID": "01G0FDP32PGC6S2Z38KJZ9QRQP" } } ]

So it's certainly possible to catch that. The problem is I have no idea if this could have unintended side effects or what other errors might look like, if the GQL error message format is consistent etc.

Here's a scuffed proof of concept: https://github.com/apo86/plugin.video.twitch/commit/9d02ea152099ddf144f9aac1022e6b965c3f0a09

Maybe this is something anxdpanic wants to look at in the future, for now it is what it is.
