ClearML Auto_Scaler Incorrectly Calling spin_up_worker

Describe the bug

When clearml/automation/auto_scaler.py calls clearml/automation/aws_driver.py's spin_up_worker function, it uses an incorrect parameter name.

Pretty sure the fix would just be changing resource=resource_conf to resource_conf=resource_conf in line 339 of auto_scaler.py, as aws_driver.py expects a resource_conf parameter. This appears to have been introduced in the last commit, as before the parameters were not explicitly named.

To reproduce

Attempt running an aws autoscaler on the current version of ClearML (7-23-2026)

Expected behaviour

When autoscaler attempts to spin up a worker, it should successfully do so.

Environment

  • Server Type: self hosted
  • ClearML SDK Version 2.1.10
  • ClearML Server Version: 3.24.1
  • Python Version: 3.12
  • OS: Linux
