I don't think it is a good idea SDK to create entire directory tree. It is user's responsibility to have correct file_path. BTW this is not temporary directory rather minio-py creates temporary file under the directory.

[Laisky]

file_path is correct and exists, the problem is {stat.etag} contains a /, that make it become a sub-directory that doesn't exists.

[balamurugana]

Send a fix to sanitize etag here using helpers.queryencode()
