amazon-s3 - 气流，BashOperator 错误“[Errno 2] 没有这样的文件或目录：'bash'：'bash'”

Question

我在 EC2、AWS 上使用 MWAA 气流。我有这个错误信息：第 1 行 -

*** Failed to verify remote log exists s3://airflow-xxx-xxx/logs/testedeoperadores/testebatch/2021-09-20T14:32:52.150650+00:00/1.log.

An error occurred (403) when calling the HeadObject operation: Forbidden

*** Falling back to local log

*** Reading local file: /var/log/airflow/testedeoperadores/testebatch/2021-09-20T14:32:52.150650+00:00/1.log

结束线 -

"File "/usr/lib64/python3.7/subprocess.py", line xxxx , in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)

FileNotFoundError: [Errno 2] No such file or directory: 'bash': 'bash'

请有人知道问题是什么以及如何解决？
