MinioAdmin.policy_add() triggers an mc deprecation error

[ctengel]

Upon calling

minio.MinioAdmin().policy_add()

The following error is returned:
subprocess.CalledProcessError: Command '['/home/minio/mc', '--json', 'admin', 'policy', 'add', 'alias', 'policy', 'policy.json']' returned non-zero exit status 1.

Upon closer investigation, it appears that mc admin policy add is being run, and on recent versions of mc, the following error is returned from that
mc: <ERROR> Deprecated command. Please use 'mc admin policy create' instead.

minio-py version 7.1.5 ; mc version RELEASE.2023-08-08T17-23-59Z

Assuming this was a recent change to mc, I am guessing minio-py`s minioadmin.py needs to be slightly changed to accommodate this.

Good news - looks like it has already been fixed by #1277

Perhaps a new release is in order so that way those who are installing this via pip etc can benefit from the fix?

Stay tuned!
