Elasticsearch Python Client's LicenseClient.post fails

Elastic Stack Elasticsearch
1

Hi,

We have upgrade from 7.17.1 to 8.6.2. We are using the Elasticsearch Python Client. We are using LicenseClient.post which was working in 7.17.1 but now is failing with 8.6.2.

I get this error from the client
ApiError(500, 'null_pointer_exception', 'Cannot invoke "String.toLowerCase(java.util.Locale)" because "name" is null')

Is this a bug in the client? When I use a curl command it is successful.

This is how we use it

from elasticsearch import Elasticsearch
from elasticsearch import client as es_client

es_cluster= Elasticsearch([es_addr + es_path],
                          http_auth=(es_user, es_password),
                          verify_certs=(pem_crt_file_full_path is not None) and do_verify_certs,
                          ca_certs=pem_file,
                          client_cert=client_crt_file_full_path,
                          client_key=client_key_file_full_path,
                          ssl_show_warn=True)

connected = es_config.ping()

<snip>

license_client = es_client.LicenseClient(es_cluster)

with open(license_file_full_path, 'r') as license_fd:
    payload = license_fd.read()
    license_return = license_client.post(license=payload)

Client info from es_config.info()

I've had a quick scan in the documentation and I don't see anything obviously wrong with the usage. Can you raise a potential bug as a GitHub issue on the client?
