trying to insert records from CSV file to dynamodb but not getting inserted

Hi , i try to insert just two records from csv file to DynamoDB the below is the python code

    with open(csv_file_path, 'r') as csvfile:
          csvreader = csv.reader(csvfile)

           header = next(csvreader)
            try:
                for row in csvreader:
                  # Construct an item for DynamoDB
                   item = {header[i]: row[i] for i in range(len(header))}
                  # Insert the item into DynamoDB
                   table.put_item(Item=item)

                  print("Data inserted into DynamoDB table.")
             except Exception as e:
                          print(f"Error: {e}")
