I’m working on a project to read Minecraft .mca files, scan for container entities (chests, shulker boxes, furnaces, barrels), and save their contents into spreadsheets using anvil-parser. However, I’m encountering issues accessing the data correctly.

import os
import anvil
import json
import pandas as pd

def scan_chunk_for_containers(chunk):
    containers = []
    for entity in chunk.entities:
        if entity['id'] in ['minecraft:chest', 'minecraft:shulker_box', 'minecraft:furnace', 'minecraft:barrel']:
            containers.append(entity)
    return containers

def process_region_file(region_file_path, output_folder):
    region = anvil.Region.from_file(region_file_path)
    all_containers = []
    for chunk_x in range(32):
        for chunk_z in range(32):
            if region.chunk_location(chunk_x, chunk_z) is not None:
                try:
                    chunk = region.get_chunk(chunk_x, chunk_z)
                    containers = scan_chunk_for_containers(chunk)
                    all_containers.extend(containers)
                except anvil.errors.ChunkNotFound:
                    continue

    if all_containers:
        output_file_path = os.path.join(output_folder, os.path.basename(region_file_path) + '_containers.json')
        with open(output_file_path, 'w') as output_file:
            json.dump(all_containers, output_file, indent=4)
        
        # Convert to DataFrame and save as spreadsheet
        df = pd.json_normalize(all_containers)
        spreadsheet_path = os.path.join(output_folder, os.path.basename(region_file_path) + '_containers.xlsx')
        df.to_excel(spreadsheet_path, index=False)
        print(f"Saved container data to {spreadsheet_path}")

def main():
    region_folder = "path goes here" 
    output_folder = "output path goes here"
    
    if not os.path.exists(output_folder):
        os.makedirs(output_folder)
    
    for file_name in os.listdir(region_folder):
        if file_name.endswith('.mca'):
            region_file_path = os.path.join(region_folder, file_name)
            process_region_file(region_file_path, output_folder)

if __name__ == "__main__":
    main()

I get the following error:

AttributeError: 'Chunk' object has no attribute 'sections'

How can I correctly access container entities? I tried some other ways but I feel like at this point I have no clue. The world is 1.20.4. I’d greatly appreciate any help!
