Limit is not working for AWS Lambda function

Question

I have a lambda function to fetch the items from dynamoDB. I have already set Limit: 100 but its not working and it gives the response as 413 - Payload Too Large.

Here is my code and I am using it with documentClient.query:

   {
      TableName: <tableName>,
      IndexName: <index-value>',
      ScanIndexForward: false,  
      KeyConditionExpression: '#status = :status',
      FilterExpression: filterExpression,
      ExpressionAttributeNames: {
        "#status": "status"
      },
      ExpressionAttributeValues: expressionAttributeValues,
      Limit: 100
    }; 

Kindly share your inputs.

Thank you.
