Object of type bytes is not JSON serializable

A function is returning a dictionary, which has data of type byte. Because it's inside, it gave a dictionary, I couldn't do a simple conversion, using

value.decode('ISO-8859-1')

I would need to go through the entire dictionary and its internal data certifying the data type to overwrite it with the decode. To simulate, I left an example code that returns the same error:

import json

dictionary ={ 
  "id": "04", 
  "name": "sunil", 
  "code": b"HR"
} 
      
json_object = json.dumps(dictionary, indent = 4) 
print(json_object)

I would like to convert this internal byte data inside a dictionary into some str, so that I could generate the json .

The previous solution is correct, but it has an issue with a local variable. It will return an error:

cannot access local variable 'key' where it is not associated with a value.

Just modify the code to be:

def decodeDictionary(dictionary):
if type(dictionary) == dict:
    for key in dictionary.keys():
        dictionary[key] = decodeDictionary(dictionary[key])
elif type(**dictionary**) == bytes:
    dictionary = dictionary.decode('ISO-8859-1') 
return dictionary

I solved my problem with this recursive function.

def decodeDictionary(dictionary):
    if type(dictionary) == dict:
        for key in dictionary.keys():
            dictionary[key] = decodeDictionary(dictionary[key])
    elif type(dictionary[key]) == bytes:
        dictionary = dictionary.decode('ISO-8859-1') 
    return dictionary

import json

dictionary ={ 
  "id": "04", 
  "name": "sunil", 
  "code": b"HR".decode('UTF-8')
} 
      
json_object = json.dumps(dictionary, indent = 4) 
print(type(json_object))

Not sure if your dict had a error in it? But if not try this?
