这个错误通常是由于使用无效的参数或缺失参数引起的。为了解决此问题，需要检查自动扩展组的配置信息，特别是关于Launch Configuration和Scaling Policies的部分。下面是一个示例Python代码片段，说明如何创建一个具有正确参数的自动扩展组：

import boto3

# Create autoscaling client
autoscale_client = boto3.client('autoscaling')

# Create launch configuration
response = autoscale_client.create_launch_configuration(
    LaunchConfigurationName='example-launch-config',
    ImageId='ami-0d8f6eb4f641ef691',
    InstanceType='t2.small',
    SecurityGroups=[
        'example-security-group',
    ],
    KeyName='example-key-pair',
    IamInstanceProfile='example-iam-role',
)

# Create scaling policy
response = autoscale_client.put_scaling_policy(
    AutoScalingGroupName='example-autoscaling-group',
    PolicyName='example-scaling-policy',
    PolicyType='StepScaling',
    StepScalingPolicyConfiguration={
        'AdjustmentType': 'PercentChangeInCapacity',
        'Cooldown': 300,
        'StepAdjustments': [
            {
                'MetricIntervalLowerBound': 0,
                'MetricIntervalUpperBound': 10,
                'ScalingAdjustment': 10,
            },
            {
                'MetricIntervalLowerBound': 10,
                'MetricIntervalUpperBound': 20,
                'ScalingAdjustment': 20,
            },
            {
                'MetricIntervalLowerBound': 20,
                'ScalingAdjustment': 30,
            },
        ]
    }
)

# Create autoscaling group
response = autoscale_client.create_auto_scaling_group(
    AutoScalingGroupName='example-autoscaling-group',
    LaunchConfigurationName='example-launch-config',
    MinSize=2,
    MaxSize=10,
    DesiredCapacity=5,
