Google API service object is not created when I make exe file - python-3.x

Question

I'm trying to make an app that fetches data from CSV and adds events to Google Calendar using Google API Client in python. Given below is my code for creating a service object.
def create_service(client_secret_file, api_name, api_version, *scopes, prefix=''):
CLIENT_SECRET_FILE = client_secret_file
API_SERVICE_NAME = api_name
API_VERSION = api_version
SCOPES = [scope for scope in scopes[0]]
cred = None
working_dir = os.getcwd()
token_dir = 'token files'
pickle_file = f'token_{API_SERVICE_NAME}_{API_VERSION}{prefix}.pickle'
### Check if token dir exists first, if not, create the folder
if not os.path.exists(os.path.join(working_dir, token_dir)):
os.mkdir(os.path.join(working_dir, token_dir))
if os.path.exists(os.path.join(working_dir, token_dir, pickle_file)):
with open(os.path.join(working_dir, token_dir, pickle_file), 'rb') as token:
cred = pickle.load(token)
if not cred or not cred.valid:
if cred and cred.expired and cred.refresh_token:
cred.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRET_FILE, SCOPES)
cred = flow.run_local_server()
with open(os.path.join(working_dir, token_dir, pickle_file), 'wb') as token:
pickle.dump(cred, token)
try:
print(CLIENT_SECRET_FILE, API_SERVICE_NAME, API_VERSION, SCOPES, cred)
service = build(serviceName=API_SERVICE_NAME, version='v3', http=SCOPES[0], developerKey="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")
# service = build(API_SERVICE_NAME, API_VERSION, credentials=cred)
print(API_SERVICE_NAME, API_VERSION, 'service created successfully')
return service
except Exception as e:
print(e)
print(f'Failed to create service instance for {API_SERVICE_NAME}')
And I create the service object using:
def main():
CLIENT_SECRET_FILE = 'client_secret.json'
API_NAME = 'calendar'
API_VERSION = 'v3'
SCOPES = ['https://www.googleapis.com/auth/calendar']
service = create_service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)
if __name__ == '__main__':
main()
input()
The code works perfectly when it's running using .py file. The main goal here to make an exe file. When I make the exe file an exception is raised in and the code directly prints print(f'Failed to create service instance for {API_SERVICE_NAME}')
Here is the output I get with .py file
And here is the output I get with .exe file
Is there any chance anyone could let me know if there is any possible solution for this?
