PMM-Client container exits even if sidecar option is enabled

Hi, I’m using the PMM v2.36.0 but I’m facing below error. I’m running the PMM-Client as a container.

I have enabled the sidecar option and tried to register the PMM-Client to PMM Server, so I think that PMM-Client shouldn’t get restarted but finally the entrypoint of the PMM-Client exited.

As you can see the Registering pmm-agent on PMM Server was done successfully.

It does not always occur. After several retrial, the PMM-Client can run successfully.
How can I prevent not to get restarted the PMM-Client even I enabled sidecar option?
