Having error when I am trying to execute the python file in Ec2 (Windows) instance using lambda trigger

I am attempting to execute a Python file in an EC2 (Windows) instance through a lambda trigger function when a file is uploaded to an S3 bucket.

My Code

import boto3

def lambda_handler(event, context):
    # Specify the target region where the EC2 instance is located
    target_region = 'us-west-2b'  # Replace with the desired region code

    # Initialize SSM client for the target region
    ssm_client = boto3.client('ssm', region_name=target_region)

    # Specify the EC2 instance ID in the target region
    instance_id = '[ID]'  # Replace with the desired instance ID

    directory = 'C:/Users/Administrator/Desktop/Automation'
    

    # Specify the Python file you want to run on the EC2 instance
    python_file = 'first.py'
    
    command = f'cd {directory} && python {python_file}'

    # Build the command to run the Python file
    # command = f'python {python_file}'

    # Send the command to the specified instance
    response = ssm_client.send_command(
         InstanceIds=[instance_id],
         DocumentName='AWS-RunShellScript',
         Parameters={'commands': [command]}
     )

    return {
        'statusCode': 200,
        'body': response
    }

But When I run the code It throws error

Can Anyone help me to resolve this issue?
