Understanding the Error

The error message you're seeing indicates that the data you're trying to work with is in bytes format instead of string format. This means that the JSON module is unable to process it, leading to the error.
Step-by-Step Solution
Follow these steps to fix the error:
Convert bytes to a string
- Use the
decode()method to convert the bytes to a string. For example:
data = data.decode('utf-8')
Use json.loads() to load the JSON string
- Once you've converted the bytes to a string, you can use the
json.loads()method to load the JSON string. For example:
json_data = json.loads(data)
Update your code to work with the JSON data
- Now that you've successfully loaded the JSON data, you can update your code to work with it.
