Hi everyone, I'm working with JSON data in Python, and I need help with converting a string representation of a JSON array into a Python list. Specifically, I'm trying to parse the following input:
'[{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]'
and expected output -
[{'name': 'Alice', 'age': 30}, {'name': 'Bob', 'age': 25}]
When I run this, I get the error: "TypeError: the JSON object must be str, bytes or bytearray, not NoneType". What could be causing this, and how can I fix it?
Any help would be appreciated!
Hi @Patel0786 ,
Python interprets this as a list of dictionaries because single quotes are valid for dictionary keys/values in Python.
This behavior is Python's native way of understanding data formats, and Workato's Python component doesn't add any special handling.
Best Practices:
1. Use double quotes for JSON keys and values when handling string representations of JSON.
2. Use json.dumps() to serialize your Python objects into valid JSON strings when needed.
3. Test your input in a Python interpreter to confirm how it’s parsed before using it in Workato.
Here is the syntax you have to use ( Sample screenshot)
Thanks and Regards,
