Import Error in One YAML DAG Prevents All DAGs From Loading

[pankajastro]

Fail to Load DAGs When a Multi-DAG YAML Contains an Import Error.

Example YAML to reproduce

default:
  default_args:
    start_date: 2024-11-11

basic_example_dag:
  default_args:
    owner: "custom_owner"
  description: "this is an example dag"
  schedule: "0 3 * * *"
  render_template_as_native_obj: True
  catchup: false
  task_groups:
    - group_name: "example_task_group"
      tooltip: "this is an example task group"
      dependencies: [task_1]
  tasks:
    - task_id: "task_1"
      operator: airflow.providers.standard.operators.bash.BashOperator
      bash_command: "echo 1"
    - task_id: "task_2"
      operator: airflow.providers.standard.operators.bash.BashOperator
      bash_command: "echo 2"
      dependencies: [task_1]
    - task_id: "task_3"
      operator: airflow.providers.standard.operators.bash.BashOperator
      bash_command: "echo 3"
      dependencies: [task_1]
      task_group_name: "example_task_group"


basic_example_dag2:
  default_args:
    owner: "custom_owner"
  description: "this is an example dag"
  schedule: "0 3 * * *"
  render_template_as_native_obj: True
  catchup: false
  task_groups:
    - group_name: "example_task_group"
      tooltip: "this is an example task group"
      dependencies: [task_1]
  tasks:
    - task_id: "task_1"
      operator: airflow.operators.bash.BashOperator
      bash_command1: "echo 1"
    - task_id: "task_2"
      operator: airflow.providers.standard.operators.bash.BashOperator
      bash_command: "echo 2"
      dependencies: [task_1]
    - task_id: "task_3"
      operator: airflow.providers.standard.operators.bash.BashOperator
      bash_command: "echo 3"
      dependencies: [task_1]
      task_group_name: "example_task_group"

I suspect maybe handling exception here https://github.com/astronomer/dag-factory/blob/main/dagfactory/dagfactory.py#L235 may fix it
