I want to execute a long running task on one pod from another. For this I started using subprocess.Popen to accomplish this task which does what I need. However, subprocess.Popen is not asynchronous and thus blocks event loop which prevents other endpoints from executing while process is running. To make this task asynchronous, I switched to asyncio.create_subprocess_exec, however I am getting errors which I am understanding how to fix. Here is the command that I am executing, which works on `subprocess.Popen'

kubectl exec -n ns1 devpod-654fcd84dd-r7spk -- /bin/sh -c llamafactory-cli train /home/llama-factory-runtime/.tmpfiles/e2ece994-7f10-442c-aae4-e938381fb67a.yaml > .tmpfiles/e2ece994-7f10-442c-aae4-e938381fb67a.log 2>&1

This is the error I am getting. Can someone help me understand the cause and possible solution to this error? I am thinking, it has to do with where the command or kubectl is executed, but I am fully certain.

I tried debugging the code, but haven't found tangible solution.
