Need help with add-on rebuild automation

Hi,

I want to create an automation that will rebuild one of my add-on daily. Before I was using hassio.addon_stdin but this service is discontinued. So now I switched to shell command instead.

Here’s what I have in configuration.yaml

shell_command:
    cloudflare_argo: ha addons rebuild bc9cb2be_cloudflare-argo

But I kept getting this error

Error running command: `ha addons rebuild bc9cb2be_cloudflare-argo`, return code: 127
NoneType: None

I’d like to mention that I have private SSH key set up.

Thanks in advance.
