If policy file is empty, mc requests the user provides a Content-Length header #5108
Description
Expected behavior
When attempting to create a policy with the mc client, a empty policy document should cause the client to error out with a helpful error message.
Actual behavior
The mc client tells the user to provide a Content-Length header, which is not very helpful to the user, especially a newbie.
Steps to reproduce the behavior
~$ cat badpolicy.json
~$ ~/minio/mc/RELEASE/2024-11-21T17-21-54Z/mc admin policy create local9000 badpolicy badpolicy.json
mc: <ERROR> Unable to create new policy. You must provide the Content-Length HTTP header.
mc --version
~$ ~/minio/mc/RELEASE/2024-11-21T17-21-54Z/mc admin info local9000
● localhost:9000

Other notes
I haven't tested with malformed JSON or valid JSON but mismatched with the policy schema - not sure what error messages those might return
