cached file cannot be found in the next hit

My workflow will cache llvm/lib and llvm/bin , and it succeeded at the first time: https://github.com/hellodword/MyApplication/actions/runs/119157969

But the cached files cannot be found at the next time (but the cache key can be hitted): https://github.com/hellodword/MyApplication/actions/runs/119660612

I tried a lot to find out the reason:

• I deleted the llvm/bin folder so the whole size of llvm is 290MB, it failed;
• With another workflow I cached a same folder structure, and use dd to create files so that the folder size can reach the same size (290MB), it succeeded;

Is it a bug or my usage problem? Any idea about this? Thanks.

just overlooked at step Releasing using Hub, there are branch switching action Switched to a new branch 'master' and your ollvm folder was likely be stashed and hence, the later step Post Cache multiple paths could not find any patterns matched. btw, the path ollvm is correct in your case.
