@Marvin ive run a flow in a dockerized context for the first time. im running into issues with a cached task, that was cached locally in a prior run. How do I solve the issue of refreshing the cache or invalidating when changing the execution envirnment so that i do not get errors such as ValueError: Path /root/.prefect/storage/a126416cdf0045eaaa6909d4c9350f40 does not exist.

When changing the execution environment, cached tasks from previous runs can sometimes lead to issues like the one you're facing. Here are steps to address the cache-related error you've encountered: 1. If you're using Prefect 2.x, check if you have specified custom cache settings for your tasks. You might need to adjust the
cache_key_fn
parameter or other cache-related configurations. 2. Ensure that your new environment has access to the cache directory or configure a different cache storage that is accessible within the Docker context. 3. If necessary, you can invalidate the cache manually by changing the inputs to the task such that the custom
cache_key_fn
generates a new key, thereby creating a new cache entry. 4. Also, ensure that your flow and tasks are designed to handle dynamic environments, i.e., avoiding hardcoded paths that might not exist in different environments. Since the provided excerpts don't detail exactly how to handle cache invalidation when changing environments in Prefect 2.x, you might want to consult the Prefect documentation or their community forum for more specific guidance on this matter. If you've made changes and the problems persist, or for more detailed steps tailored to your situation, you could check for relevant issues on GitHub or Prefect's community channels. Would you like me to search GitHub issues for problems similar to yours, or assist you with anything else?
