Error when private message sent through deso.py

When a private message is sent though [deso.py](https://github.com/AdityaChaudhary0005/DeSo.py) library, the sender is shown the below message in the inbox from bitclout.com and diamondapp.com
``
The receiver receives the correct message though. But the sender has issues in seeing the message sent.
Issue mentioned in https://github.com/AdityaChaudhary0005/DeSo.py/issues/20
Is it because of mistake in [deso.py](https://github.com/AdityaChaudhary0005/DeSo.py) or in deso frontends?

Start by reproducing a private message sent through the linked deso.py issue and compare what the sender sees in bitclout.com and diamondapp.com with what the receiver sees. Review the linked DeSo.py issue for the reported behavior; done means the sender can view the sent message without the non-decryptable error, with the responsible component identified.
