WebSocket crashing on random occasions

[jaspertanlol]

I am using WebSocket in Robyn to send content to my frontend. At random times after the last massage has been sent I will get a crash.

thread 'actix-rt|system:0|arbiter:0' panicked at src\executors\web_socket_executors.rs:89:62: called Result::unwrap()on anErrvalue: PyErr { type: <class 'TypeError'>, value: TypeError("'NoneType' object cannot be converted to 'PyString'"), traceback: None } note: run withRUST_BACKTRACE=1 environment variable to display a backtrace

What is causing this issue?
