(aws-mwaa): unable to use existing LogGroup via via mwaa.CfnEnvironment

I am unable to use existing LogGroups via mwaa.CfnEnvironment. cdk deploy raised error

Reproduction Steps

class AirflowStack(core.Stack):

    def __init__(self, scope: core.Construct, construct_id: str, environment: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        scheduler_log = aws_logs.LogGroup(
                scope=self,
                id=f'airflow-cloudwatch-{environment}-Scheduler',
                log_group_name=f'/aws/airflow/{environment}/Scheduler',
                encryption_key=key,
                removal_policy=core.RemovalPolicy.DESTROY,
                retention=aws_logs.RetentionDays.INFINITE
            )

        logging_configuration = aws_mwaa.CfnEnvironment.LoggingConfigurationProperty(
            scheduler_logs=aws_mwaa.CfnEnvironment.ModuleLoggingConfigurationProperty(
                enabled=True,
                cloud_watch_log_group_arn=scheduler_log.log_group_arn,
                log_level='WARNING'
           )
        )

        mwaa_env = aws_mwaa.CfnEnvironment(
            scope=self,
            id=f'airflow-{environment}',
            name=f'{environment}',
            airflow_version='1.10.12',
            dag_s3_path='dags',
            environment_class='mw1.small',
            execution_role_arn=role.role_arn,
            kms_key=key.key_arn,
            logging_configuration=logging_configuration,
            max_workers=10,
            network_configuration=network_configuration,
            requirements_s3_path='requirements.txt',
            source_bucket_arn=bucket.bucket_arn,
            tags=None,
            webserver_access_mode='PRIVATE_ONLY'
        )

What did you expect to happen?

Successful deployment of the stack

My solution is

1. Create LogGroups

       log_groups = {}
        for log_group in ['DAGProcessing', 'Scheduler', 'Task', 'WebServer', 'Worker']:
            log_groups[log_group] = aws_logs.LogGroup(
                scope=self,
                id=f'{environment}-{log_group}',
                log_group_name=f'airflow-{environment}-{log_group}',
                removal_policy=core.RemovalPolicy.DESTROY,
                retention=aws_logs.RetentionDays.SIX_MONTHS
            )

1. Create LoggingConfigurationProperty

        logging_configuration = aws_mwaa.CfnEnvironment.LoggingConfigurationProperty(
            dag_processing_logs=aws_mwaa.CfnEnvironment.ModuleLoggingConfigurationProperty(
                enabled=True,
                cloud_watch_log_group_arn=log_groups['DAGProcessing'].log_group_arn,
                log_level='INFO'
            ),
            scheduler_logs=aws_mwaa.CfnEnvironment.ModuleLoggingConfigurationProperty(
                enabled=True,
                cloud_watch_log_group_arn=log_groups['Scheduler'].log_group_arn,
                log_level='INFO'
            ),
            task_logs=aws_mwaa.CfnEnvironment.ModuleLoggingConfigurationProperty(
                enabled=True,
                cloud_watch_log_group_arn=log_groups['Task'].log_group_arn,
                log_level='INFO'
            ),
            webserver_logs=aws_mwaa.CfnEnvironment.ModuleLoggingConfigurationProperty(
                enabled=False,
                cloud_watch_log_group_arn=log_groups['WebServer'].log_group_arn,
                log_level='INFO'
            ),
            worker_logs=aws_mwaa.CfnEnvironment.ModuleLoggingConfigurationProperty(
                enabled=True,
                cloud_watch_log_group_arn=log_groups['Worker'].log_group_arn,
                log_level='WARNING'
            )
        )

1. And use it in mwaa

        mwaa_env = aws_mwaa.CfnEnvironment(
            scope=self,
            id='airflow',
            name=f'{environment}',
            airflow_configuration_options=None,
            airflow_version='1.10.12',
            dag_s3_path='dags',
            environment_class='mw1.small',
            execution_role_arn=role.role_arn,
            logging_configuration=logging_configuration,
            max_workers=10,
            network_configuration=network_configuration,
            plugins_s3_object_version=None,
            plugins_s3_path=None,
            requirements_s3_object_version=None,
            requirements_s3_path='requirements.txt',
            source_bucket_arn=bucket.bucket_arn,
            tags=None,
            webserver_access_mode='PRIVATE_ONLY',
            weekly_maintenance_window_start='SUN:03:30'
        )
