Session is closed abnormally, when CloseReason { code: Error, description: <some_very_long_text> }

[Loaki07]

Recently, while using actix_ws in one of our projects. There is a bug when the session closes abnormally and the client gets a 1006 error code.

On debugging further, it was particularly when there was an error with the description to the internal error (some long text with db code and details) which was long string.

I was able to fix it by sending a short string and only then the client gets 1011 error code.

Curious about this behavior, any reason, why?

Thanks in advance!
