cleanupHttpCache: invalid cache data on Bitbucket Server

[amezin]

What would you like help with?

I think I found a bug

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Bitbucket Server, Docker image ghcr.io/renovatebot/renovate:37.296.0-full

Please tell us more about your question or problem

Since a recent update I'm getting "cleanupHttpCache: invalid cache data":

• once for every repository if RENOVATE_REPOSITORY_CACHE=enabled

• twice if RENOVATE_REPOSITORY_CACHE=reset

• no warnings if RENOVATE_REPOSITORY_CACHE=disabled

Removing all directories doesn't seem to help.
