The _get_cache_key method calls os.stat(asset) without checking if the file exists first. This will raise FileNotFoundError for non-existent files. However, the file existence check happens later in upload_asset at line 44. This causes cache key generation to fail before the proper error handling. Consider adding existence check in _get_cache_key or handling the exception appropriately.

Suggested change
stat = os.stat(asset)
try:
stat = os.stat(asset)
except FileNotFoundError:
raise FileNotFoundError(f"File not found: {asset}")
