[2022-06-19 15:33:19.240 +10:00] [INF] Executing "Analyze episodes"

After a new minutes dashboard [Running tasks] starting to count from 0.01% but not sure if it's working as I can't find any new files and nothing else shows in the logs.

Are we able to have a log file for this that shows every what is going on and more info on how this plugin works for those who have limited IT knowledge? I understand how it works but not where the files are stored? I was thinking inside the shows folder?

After 5 seconds it auto skipped on the web client.

I am seeing this same error on a fresh docker install
Intro Skipper 0.1.5.0
Jellyfin 10.8.0
Linuxserver.io docker image on ubuntu 20.04 host

With Cache fingerprints to disk disabled I get the same error as OP, when enabled it still fails but provides a different error:

ConfusedPolarBear.Plugin.IntroSkipper.FingerprinterTask: Unable to analyze "redacted" season 5: cache miss: "System.Collections.Generic.KeyNotFoundException: The given key '8f22f85b-6830-6609-d07b-88f80b50a728' was not present in the dictionary.

at ConfusedPolarBear.Plugin.IntroSkipper.FingerprinterTask.<>c__DisplayClass19_0.b__0(KeyValuePair`2 season)"

Not sure if that is related or a separate issue, but figured it was worth mentioning.

The next version of the plugin (v0.1.6 [beta version]) will log the name of each show and season number as the plugin is starting to analyze it.

I understand how it works but not where the files are stored?

After a season is analyzed, the timestamps of all introductions are serialized as XML to CONFIG_DIR/plugins/configurations/intros/intros.xml

This should also be fixed in v0.1.6.
