i am getting KERNEL_NAME is empty in newly created remote kernel pod while launching ipython kernel in jupyterhub vai JEG. is this error because of this empty KERNEL_NAME ? in JEG pod i can see {"name":"KERNEL_NAME","value":"python_kubernetes"}]

launch_ipykernel] JSON Payload 'b'{"shell_port": 55055, "iopub_port": 44507, "stdin_port": 56833, "control_port": 60735, "hb_port": 57375, "ip": "0.0.0.0", "key": "17fd8e85-7e4d-4e29-946e-9a6975c2b0cc", "transport": "tcp", "signature_scheme": "hmac-sha256", "kernel_name": "", "pid": 9, "pgid": 7, "comm_port": 33997, "kernel_id": "d80c56dc-8da1-4da4-a023-a65cc99ee0ca"}'

looks like empty string passing to json.decoder() function as per error, am i missing passing any extraEnv in jupyterhub yaml ?
