        print(e.message)

Error:

TypeScript

 unsupported operand type(s) for +: 'NoneType' and 'str'

TL;DR

The developer is encountering an error in their Python SDK code. The error states "unsupported operand type(s) for +: 'NoneType' and 'str'". They mention that the error just started occurring today and they are providing the correct data type in the attribute. The provided code shows a function called `addofficial` which is a Discord bot command. It takes a mention of a user as an argument and tries to add that user as an official to a database using the `addOfficialToDB` function. If the `user` argument is not provided, it sends a message asking for the user to be mentioned or their ID
