## TL;DR

Fix: Contributor lzzzzzzzzz: bump the sandbox image from 0.2.1 to 0.2.4 to fix inconsistent execution after importing third-party libraries. Maintainer crazywoola linked the dify-sandbox FAQ: the sandbox blocks syscalls not on its allowlist (file io, networking, etc.), so libraries needing disallowed syscalls fail - check the FAQ's ALLOW_SYSCALLS list when a library still misbehaves after the version bump.
