Cache getting incorrectly accessed/read

[JustinBack]

I am accessing flagsmith in a docker container via a PHP CMS and everytime after restarting I have to manually clear the cache folder (removing the cache folder via the entrypoint doesnt work aswell) due to an error that the cachedCall is null.

The cache folder is empty and after deleting it it works.

Any clue on what the issue is an how to hotfix it? Running on Tag 2.1.1

I just noticed deleting the subfolders of the symfony-cache folder is not enough. The symfony-cache folder itself has to be completely deleted.

Thanks for raising the issue @JustinBack . From the first look, it looks like this could be a docker copy versus docker volume problem, because it refreshes on restart. Can you confirm if you are using COPY in your docker file? If not, can we have a look at your dockerfile? and docker-compose (if any), so we can build this at our end?

It does use copy however not the /tmp/ folder.
