I'm developing a custom skill with no TTS interaction, all of skill output was recorded by a human, so we have a lot (thousands) of audio files, stored on self-hosted swift s3. this s3 is shared with other products and delivers hundreds of millions of requests worldwide.
Sometimes (sporadically) the application unexpectedly stops, with no message. It just turns its light off, and after one second, it gives a last flash. (see the video https://drive.google.com/file/d/16CzqDporcxeiValF-wTjcbbH5b9A9Iqq/view?usp=sharing). It would have one more audio file to play.
I believe it's somehow related to our s3 (timeout maybe?) but I didn't find a place to check or get a log.
Have anyone seen this kind of error before? Or is there a code of error, to understand this kind of stop without a message?
Is there a way to get logs to debug this problem?
What way would you start the investigation?
