when I try to configure it in the yaml :
resources:
  jobs:
    ofirtest:
      name: ofirtest
      tasks:
        - task_key: ofirtest
          notebook_task:
            notebook_path: /Workspace/Users/username/Untitled Notebook
              2025-09-15 14:22:51

            source: WORKSPACE
          environment_key: default
      queue:
        enabled: true
      environments:
        - environment_key: default
          spec:
            environment_version: "4"
      performance_target: PERFORMANCE_OPTIMIZED  

this is how it looks like:
