datetime json dump or load problem during writing and reading file-CodePudding

i have this piece of code in testing currently

from_api_response_data = [
  {
    "active": True,
    "available": True,
    "test1": True,
    "test2": "Testing Only",
    "test3": False,
    "test_name": "Tester 1",
    "id": "12345abcxyz",
    "test_url": {
      "url": "/something/others/api/v1/abc123"
    }
  },
  {
    "active": True,
    "available": True,
    "test1": False,
    "test2": "This also a test",
    "test3": False,
    "test_name": "Tester 2",
    "id": "12345abcxyz678",
    "test_url": {
      "url": "/something/others/api/v1/abc1234"
    }
  }
]

filename = 'testingfile.json'
today = datetime.datetime.now().isoformat()

from_api_response_data.append(
    {
        'last_updated_date': today
    }
)

Path(filename).write_text(
    json.dumps(from_api_response_data, default=vars, indent=2)
)

test_file_json_read = json.loads(
        Path(filename).read_text()
    )

for test in test_file_json_read:
    if test['available']:
        print("true available")

what i am trying to simulate is getting data from api and append updated date and write the data into json file. If i remove that part in appending date, my code works fine when finding test['available']

from console output

 true available
 true available

but with the date append, i will have this error

 if test['available']:
  KeyError: 'available'

i am not sure why i am not able to read the test['available'] if the date is appended

this is what my testingfile.json showing

[
  {
    "active": true,
    "available": true,
    "test1": true,
    "test2": "Testing Only",
    "test3": false,
    "test_name": "Tester 1",
    "id": "12345abcxyz",
    "test_url": {
      "url": "/something/others/api/v1/abc123"
    }
  },
  {
    "active": true,
    "available": true,
    "test1": false,
    "test2": "This also a test",
    "test3": false,
    "test_name": "Tester 2",
    "id": "12345abcxyz678",
    "test_url": {
      "url": "/something/others/api/v1/abc1234"
    }
  },
  {
    "last_updated_date": "2022-11-25T09:48:12.765296"
  }
]
