Ethereum: TypeError: Object ‘NoneType’ is not writable: JSON file

I’m happy to help you resolve your issue. However, I don’t see any code provided in your message. Could you please share the full code snippet that’s causing the error? This will allow me to better understand the context and provide a more accurate solution.

That being said, here are some potential reasons for the TypeError: 'NoneType' object is not subscriptable error when working with JSON files using Python:

  • JSON file is empty or None: Make sure your JSON file exists and contains at least one key-value pair. If the file is empty or doesn’t exist, you’ll get a NoneType error.

  • Invalid JSON syntax: Ensure that your JSON file has valid syntax. Check for any syntax errors, such as missing or mismatched brackets.

  • File not loaded correctly: The json module loads files from the current working directory by default. If your JSON file is located elsewhere, you’ll need to provide the full path.

  • Data corruption

    Ethereum: TypeError: 'NoneType' object is not subscriptable: JSON file

    : Corrupted data in your JSON file might be causing issues when trying to subscript it.

Here’s a step-by-step guide to help you troubleshoot and resolve the issue:

۱. Verify your JSON file

Open your JSON file in a text editor or IDE. Check if the contents match what you expect. If everything looks correct, proceed to the next step.

۲. Ensure data is loaded correctly

Check if the json module can load the file successfully:

import json

with open('your_file.json') as f:

try:

data = json.load(f)

print(data)





Should print the loaded JSON data

except (FileNotFoundError, json.JSONDecodeError):

print("Error: File not found or JSON decoding error")

۳. Provide the full path to your JSON file

If you’re using a relative path, make sure it’s correct:

import json

full_path = 'path/to/your/file.json'

with open(full_path) as f:

try:

data = json.load(f)

print(data)

Should print the loaded JSON data

except (FileNotFoundError, json.JSONDecodeError):

print("Error: File not found or JSON decoding error")

۴. Check for corrupted data

If you suspect that your JSON file is corrupted, try loading a different version of it:

import json

with open('corrupted_file.json') and f:

try:

data = json.load(f)

print(data)

Should print the loaded JSON data (or an error message if it's corrupt)

except (FileNotFoundError, json.JSONDecodeError):

print("Error: File not found or JSON decoding error")

۵. Verify your code

Double-check your code to ensure you’re loading and processing the JSON file correctly.

If none of these steps resolve the issue, please provide more details about your code and JSON file (e.g., specific lines of code, file paths), and I’ll be happy to help further!
