Investigate need to clear youtube.js cache when rotating

As those are my messages in the screenshot and the title of the issue implies that there is a misunderstanding of what I said. All you need to change is to add enable_session_cache: false when calling Innertube.create() that will make YouTube.js ignore the existing session cache and prevent it from writing a new one. You still want to keep the caching for the player.js for example.

If you really want to go with the approach of clearing the cache every time you rotate, there is no point creating the cache in the first place. The whole point of the cache is to remember things for the next time you call Innertube.create() so if you clear it each time before you call Innertube.create(), there will be nothing for it to read, because you deleted what the previous Innertube instance wrote to the cache.

Thanks for the message. Indeed that's much clearer.

It's just an issue to remind myself to investigate.

So, about 4 days ago I completely rebuilt the images on the servers with cache cleanup (docker compose build --no-cache) and I again caught a moment when invidious-campanion doesn't return streamingData. This time I manually edited the main.ts file, added enable_session_cache: false to the await Innertube.create({ ... }) constructor, then ran the docker compose build && docker compose up command. Everything is working fine again. I'll wait another 4 days and report back with the results. I don't know exactly how to check that po_token and visitorData are not cached now. But supposedly they should be updated every 5 minutes now, if I understood everything correctly.

thanks @artshevtsov. there are multiple Innertube.create, which one did you modify?

The first one, at line 53, is then passed to the poTokenGenerate function, now I see that the Innertube client is being recreated inside it, so I need to modify it also at poTokenGenerate...
I think that I need to modify this lines
if (innertubeClient.session.po_token) {
innertubeClient = await Innertube.create({ retrieve_player: false });
}

like that:

if (innertubeClient?.session?.po_token) {
    innertubeClient = await Innertube.create({ retrieve_player: false, enable_session_cache: false });
}

but it's better to define clientOptions object somewhere at main.ts, import it at potoken.ts and use at poTokenGenerate function and merge it like this using a spread operator {...clientOptions, retrieve_player: false}

if (innertubeClient?.session?.po_token) {
    innertubeClient = await Innertube.create({...clientOptions,  retrieve_player: false});
}
