Running local python code with arguments in Databricks via dbx utility

I am trying to execute a local PySpark script on a Databricks cluster via dbx utility to test how passing arguments to python works in Databricks when developing locally. However, the test arguments I am passing are not being read for some reason. Could someone help? Following this guide, but it is a bit unclear and lacks good examples. https://dbx.readthedocs.io/en/latest/quickstart.html Found this, but it also not clear: How can I pass and than get the passed arguments in databricks job

Databricks manuals are very much not clear in this area.

My PySpark script:

import sys

n = len(sys.argv)
print("Total arguments passed:", n)

print("Script name", sys.argv[0])

print("\nArguments passed:", end=" ")
for i in range(1, n):
    print(sys.argv[i], end=" ")

dbx deployment.json:

{
  "default": {
    "jobs": [
      {
        "name": "parameter-test",
        "spark_python_task": {
            "python_file": "parameter-test.py"
        },
        "parameters": [
          "test-argument-1",
          "test-argument-2"
        ]
      }
    ]
  }
}

dbx execute command:

dbx execute\
  --cluster-id=<reducted>\
  --job=parameter-test\
  --deployment-file=conf/deployment.json\
  --no-rebuild\
  --no-package

Output:

Please help :)

It turns out the parameter section format of my deployment.json was not correct. Here is the corrected example:

{
  "default": {
    "jobs": [
      {
        "name": "parameter-test",
        "spark_python_task": {
          "python_file": "parameter-test.py",
          "parameters": [
            "test1",
            "test2"
          ]
        }
      }
    ]
  }
}

I've also posted my original question in Databricks forum: https://community.databricks.com/s/feed/0D58Y00008znXBxSAM?t=1659032862560 Hope it helps someone else.
