Error Message: Resource not found for the segment 'calendars'.

[Impdevil]

Hi I'm trying to connect using application permissions for a chatbot, and I'm either receiving this error above or

"The token contains no permissions, or permissions can not be understood."

when trying to get access to specifically a calendar, I'm not really understanding where im going wrong. I'm using a blueprint to create the system I need each time, though not sure if that's the best option, here's the relevant code:

` def init(self):

    self._date = datetime.datetime.now
    self._account = None
    print("Initializing calendar connection")
    with open(os.getenv("MSCLIENTINFO")) as json_file:
        creds_dict = json.load(json_file)
    creds = (creds_dict["MSCLIENT_ID"],creds_dict["MSSECRET"])
    
    token_backend = ograph.FileSystemTokenBackend(token_path="ChatBot-NSGC-v0_3", token_filename="o365_token.txt")

    account = ograph.Account(creds,timezone="Europe/London",token_backend=token_backend, auth_flow_type="credentials", tenant_id=creds_dict["tenant-id"])

    if account.authenticate():
        print("Calendar Connection Created " + str(account))
        self._account = account
    else:
        print("Calendar Connection Failed")



def Retrieve_account(self):
    if self._account.is_authenticated == True:
        print("account connected")
        return self._account
    
    print("connection lost")
    return False

##
def Check_date_time_conflict(self, bookingdict):
    '''
        return types true = conflicts
        false = no conflicts
    '''
    account = self.Retrieve_account()
    
    sched = account.schedule()
    for potato in sched.list_calendars():
        print(potato.name)
        if potato.name == 'CalenderTesterAPI':
            print('found!')

    if self.Retrieve_account() != False:
        #onced checked the the account is correct check against the 
        
        print("potat0")
        calender = sched.get_calendar(calendar_name="CalenderTesterAPI")
        print("potat1 " + calender)
        cal_query = calender.new_query("start").equal(bookingdict['returnedTime'])
        print("Cal query "+str(cal_query))
        bookings =  calender.get_events(query=cal_query, include_recurring=True)
        print("potat2 " + str(bookings))
        for booking in bookings:
            if booking != None:
                return True
            else: return False
    else: 
        print("Account failed to connect " + str(self.Retrieve_account()))
        return False

As you can probably see I've had a look at previous issues related to this topic but I cant seem to understand where this is going wrong. The code fails at the first instantiation of sched in Check_date_time_conflict. with sched = account.schedule(resource="[email protected]") it give me the second error, I'm very sure I have setup the app registration on msgraph part so I'm sure its some issue with my code. I have the Token saved as well.

Pardon my print("potat#") its a habit for debugging that I haven't properly lost since college.

When using credentials as auth flow you need to pass a resource as you are initially authenticated as the “app”.

So just:

sched = account.schedule(resource='[email protected]')

[Impdevil]

I have that and it still seems to not work, i receive the second error
sched = account.schedule(resource="[email protected]") for potato in sched.list_calendars(): print(potato.name) if potato.name == 'CalenderTesterAPI': print('found!')

The token contains no permissions, or permissions can not be understood.

I'm sorry I'm not understanding where its drawing this from, I have the token and definitely have the app permissions set in azure

[alejcas]

Then it could be a problem with the definition of the app.

Two questions:

1.- Did you add Application permissions or delegated permissions?
1.- Did you request and have the "Admin Consent" approved?

[Impdevil]

I used application permissions
and I am the admin

I have also looked into my token and i see no permissions being sent, referring to scp after i decoded the token.

[alejcas]

I'm sorry I'm not understanding where its drawing this from

This message comes from the MS Graph Service.

The token file should contain only the ".default" scope. Correct?

[Impdevil]

I see no ".default" scope in the token

I'm using https://jwt.io/ to decrypt the token btw

[Impdevil]

I have revoked the previous app permissions and then added them again with admin consent and saved a new client secret.

but still to no avail.
