FetchThreadList() returns null

[jmbits]

I was following the examples, but I receive the following exception:

System.ArgumentNullException
HResult=0x80004003
Message=Value cannot be null.
Source=System.Private.CoreLib
StackTrace:

Any idea why this is happening?

Hello thanks for reporting this, I'll look into it when I can.
In the meantime you can edit the library code yourself if you want.
The offending line should be

fbchat-sharp/fbchat-sharp/API/GraphQl.cs

Line 281 in 8db21aa

last_name: user["name"]?.Value<string>()?.Replace(user["short_name"]?.Value<string>(), "")?.Trim(),

Something like this might do:
last_name: user["short_name"]?.Value<string>() != null ? user["name"]?.Value<string>()?.Replace(user["short_name"]?.Value<string>(), "")?.Trim() : "",
