Log exception source from flask decorator - exception

Question

I'm using a python decorator to handle exceptions in my flask app.
decorators.py
def exception(original_function=None, message='Some error occurred on our end.', app=None):
def decorator(function):
#functools.wraps(function)
def wrapper_function(*args, **kwargs):
try:
return function(*args, **kwargs)
except Exception as e:
handler(app, e)
return internal_error(message)
return wrapper_function
The handler function captures the exception details and logs or displays them.
def handler(app, e='Exception'):
exc_type, exc_obj, exc_tb = sys.exc_info()
exc_type, filename, line_no = exc_type, exc_tb.tb_frame.f_code.co_filename, exc_tb.tb_lineno
app.logger.error(f'\n+{"-" * 64}\n'
'| Exception details:\n'
f'| Message: {e}\n'
f'| Type:\t\t{exc_type}\n'
f'| File:\t\t{filename}\n'
f'| Line No:\t\t{line_no}\n'
f'+{"-" * 64}\n')
Then I use it in flask routes as:
route.py
#bp.route('/initialize/<string:uuid>/<string:method>', methods=['POST'])
#exception(app=current_app)
def initialize(uuid=None, method=None):
if not uuid:
return bad_request('No UUID')
Right now, the handler does work, however, it logs that the exception originated from decorators.py on the return function(*args, **kwargs) line. How can I log the actual file and line the exception originated?
Here is an output of the log.
