s3Download Couldn't Create Parent Directories

[emilyyujieli]

Hi

Description
l tried to use s3Download download file from s3 object storage to a specific pvc path in kubernetes pod.

            s3Download(
                    pathStyleAccessEnabled: true,
                    payloadSigningEnabled: false,
                    file: '/demo/',
                    bucket: BUCKET_NAME,
                    path: 'test/',
                    force: false
            )

However it always come to an error - "java.lang.RuntimeException: Couldn't create parent directories for /demo/test/test.txt".
l tried to check the permission in the pod and it's already root user. Meanwhile if l execute in this pod and create those folder manually, it also works.

Question
Kindly ask if there any good idea how to solve this issue?
