(Please follow this template replacing the text between parentheses with the requested information)

Expected behavior and actual behavior

workflow and params should be defined and not null inside the workflow.onComplete closure. instead both are null.

Steps to reproduce the problem

process SAY_HELLO {
  input:
    val greeting
  output:
    eval("echo $greeting, world")
  script:
    """
    sleep 1
    """
}

workflow {
  Channel.of("Hello", "Hallo", "Hola", "Bonjour")
  | SAY_HELLO
  | view

  workflow.onComplete {
    println "workflow is null: ${workflow == null ? 'yes' : 'no'}"
    println "params is null: ${params == null ? 'yes' : 'no'}"
  }
}

Program output

Hello
Hola
Bonjour
Hallo
workflow is null: yes
params is null: yes
