(cdk-CfnFlow): Unable to add task property

[shiv-lch]

Team - I'm trying to create an appflow job and one of the block is to pass 'Task Property' using 'TaskPropertiesObjectProperty' class. But it fails with below error, and I could figure out, the error points to 'task_property' .

Class reference
classCfnFlow.TaskPropertiesObjectProperty(*, key, value)

Code
myflow.CfnFlow.TaskProperty(
task_type='Map_all',
source_fields=[],
task_properties=myflow.CfnFlow.TaskPropertiesObjectProperty(key='EXCLUDE_SOURCE_FIELDS_LIST',value=[]),
connector_operator=myflow.CfnFlow.ConnectorOperatorProperty(zendesk='NO_OP')

Error
jsii.errors.JSIIError: Value did not match any type in union: Value did not match any type in union: Value did not match any type in union: Expected array type, got {"$jsii.struct":{"fqn":"@aws-cdk/aws-appflow.CfnFlow.TaskPropertiesObjectProperty","data":{"key":"EXCLUDE_SOURCE_FIELDS_LIST","value":[]}}},

Reference URL https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_appflow/CfnFlow.html#aws_cdk.aws_appflow.CfnFlow.TaskPropertiesObjectProperty

Environment
CDK CLI Version : 1.114.0 (build 7e41b6b)
Framework Version:
Language: Python.3.6.8

Any helps on this, as the CDK/class expects the key/value to be string, but the value must be an empty list '[]', below the working YAML block.

Tasks:

• TaskType: Map_all
  SourceFields: []
  TaskProperties:
  - Key: EXCLUDE_SOURCE_FIELDS_LIST
  Value: '[]'

This is closed, as passing the properties as array.
