How can I troubleshoot caching issues in GitHub Actions?

To troubleshoot caching issues in GitHub Actions, first check your cache key and paths. Are they correctly defined?

I think my cache key is correct, but the cache isn't being restored. What should I do?

Ensure that the cache is being saved correctly in previous runs. You can check the logs for any errors during the save step.

What if the cache is saved but still not restored in subsequent runs?

In that case, verify that the cache key matches exactly in both the save and restore steps. Also, check for any changes in the dependencies.

Are there any limitations on the size of the cache?

Yes, GitHub Actions has a cache size limit of 2 GB per cache key. If your cache exceeds this, it won't be saved.
