Compilation error: exit status 1

the line in ESPASyncWebServer.h currently looks like this:
return static_cast<tcp_state>(_server.status());

but it must be:
return static_cast<tcp_state>(const_cast<AsyncServer&>(_server).status());

fix by kimi.com

greetings

Edit: wrong repo. sorry.

I confirm that:

The code is ok, please search in the discussions of the librairies. This is mostly an environnement error on your end, like a wrong library version
