Strange runtime error that occur randomly.

[l-you]

Souin works. I use it as a traefik plugin. Souin version 1.7.7.

Sometimes on the website I get strange error when navigating between pages. When I go to the reverse proxy logs I have the same error each time when this happens. Any idea what can it be?

[darkweak]

Hey @l-you do you have a reproducible repository? (Sorry for the long delay, I was busy on other stuff)

[l-you]

Hi @darkweak,

I’m sorry, unfortunately I’ve already replaced the usage of Traefik + Sounin with Nginx + Traefik. I don’t have a reproduction.
