python decode JWT not containing any dots

I am given a JWT which does not contain any dots. I read somewhere that the typical format of a JWT is 3 pieces of string concatenated with 2 dots in total. Using PyJWT when I try to decode the token, I am getting the below error -

Traceback (most recent call last):
  File "/home/neelanjana/.virtualenvs/athena_env/lib/python3.7/site-packages/jwt/api_jws.py", line 180, in _load
    signing_input, crypto_segment = jwt.rsplit(b'.', 1)
ValueError: not enough values to unpack (expected 2, got 1)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/neelanjana/.virtualenvs/athena_env/lib/python3.7/site-packages/jwt/api_jwt.py", line 84, in decode
    payload, _, _, _ = self._load(jwt)
  File "/home/neelanjana/.virtualenvs/athena_env/lib/python3.7/site-packages/jwt/api_jws.py", line 183, in _load
    raise DecodeError('Not enough segments')
jwt.exceptions.DecodeError: Not enough segments

However, when I put the same token on jwt.io, it gets decoded and I am able to see the complete dictionary. Is What am I missing?

Here is my code -

import jwt

a = "someToken"
print(jwt.decode(a))

Attaching a pastebin link to the token here since it is too long to put here.

P.S. I am not married to the idea of using pyjwt. If any other library can decode it it's all the same for me.

To answer my own question, the above string is not JWT but a base64 encoded string. Using base64 decoding the actual dict was recovered.
