Getting InvalidParameterException while calling texteract analyze_document

Please find below the code, I've replaced confidential contents with **.

import re
# boto3 client
textract = boto3.client(
    'textract', 
    region_name='**', 
    aws_access_key_id='**', 
    aws_secret_access_key='**'
)



response = textract.analyze_document(
            Document={'S3Object': {'Bucket': '**/todo', 'Name': '1.pdf'}},
    
            FeatureTypes=["FORMS",],
            HumanLoopConfig={
                'FlowDefinitionArn': 'arn:aws:sagemaker:us-east-1:**:flow-definition/analyse-text',
                'HumanLoopName': 'analyse-text1',
                'DataAttributes': {
                    'ContentClassifiers': [
                        'FreeOfPersonallyIdentifiableInformation','FreeOfAdultContent'
                    ]
                },
            },
          )

Here is Full error
