I set up a gitlab ssh runner in an Azure VM, here is my Config.toml file for the runner:

concurrent = 1
check_interval = 0
shutdown_timeout = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "tfcicd"
  url = ";
  id = 45901682
  token = "glrt-..."
  token_obtained_at = 
  token_expires_at = 0001-01-01T00:00:00Z
  executor = "ssh"
  shell = "bash"
  [runners.cache]
    MaxUploadedArchiveSize = 0
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.ssh]
    user = "ubuntu"
    host = ""
    port = "22"
    identity_file = "/home/azureuser/.ssh/gitlab_rsa"

When I commit code to my gitlab repository, pipeline is successfully connect with runner, however, runner is failed to prepare environment to run my deployment script.
This is command I used to run the runner:

gitlab-runner --debug run

the command output blow logs:

What have I done to debug:

1. I used the ssh command to connect to remote machine and run bash -l in the remote machine, all works.

2. I saw from document that this file could be root cuase: /home/gitlab-runner/.bash_logout, but for me I do not have this file in my VM.
