Could not extract JSON. Youtube API returned error 500 with message: "ExecuteQuery for ChannelMiddlewareService-GetShelves failed: RET_CHECK failure (video/youtube/channels/frontend/shared/continuations/channel_middleware_token_encoding.cc:15) absl::WebSafeBase64Unescape(web_safe_token, &unescaped_token) ; OneMustSucceed: input 'mw_shelf_source_exp_continuation_unwrapper'; OneMustSucceed: input 'mw_shelf_source_exp_subgraphs'; OneMustSucceed: input 'mw_shelf_source_exp_empty_shelf_filter'; OneMustSucceed: input 'ShelfSourceExpansion__graph'; OneMustSucceed: input 'get_shelves_shelf_candidate_rank_sorter'; OneMustSucceed: input 'wrapped_main_subgraph'; OneMustSucceed: input 'pre_decoration_subgraph'; OneMustSucceed: input 'decoration_annotator_subgraph'; OneMustSucceed: input 'post_decoration_subgraph'; PropagateAllErrors: input 'GetShelvesEndpoint__graph'; PropagateAllErrors: input 'default_filter_survivor_probe_op'; PropagateAllErrors: input 'policy_enforcement_candidate_predicate'; /ChannelMiddlewareService.GetShelves RPC failed"

Yep. The error appears when you enter the channel. /channel/UCQHX6ViZmPsWiYSFAyS0a3Q for example. In some cases, refreshing the page gives the expected result, but then refreshing the page again gives this error. Sections "streams", "community", "playlists", individual playlists and individual videos do not cause this error.

Perhaps, subscriptions are not updated for the same reason. I see this error on yewtu.be invidious.snoopyta and on my own instance.

Started seeing this today on my instance as well.

[davidhfrankelcodes]

Same.

I'm also getting it, from log file after clicking to view a channel:

Yes same here and tried 6 instance. None of them work anymore.

[Abyssgrowth]

Was there an internal youtube update that caused this?

[unixfox]

Was there an internal youtube update that caused this?

Yes that's correct. If you want, you can discuss it further on matrix or IRC.

[alithechemist]

Yep. The error appears when you enter the channel. /channel/UCQHX6ViZmPsWiYSFAyS0a3Q for example. In some cases, refreshing the page gives the expected result, but then refreshing the page again gives this error. Sections "streams", "community", "playlists", individual playlists and individual videos do not cause this error.

That is because a change is being deployed to a large cluster

[garoto]

It seems it's related to how channels are now using the new @name handle/moniker format by default.

New commit fixed the issue: https://github.com/iv-org/invidious/pull/3718 Please update your invidious instance.
