Variable "WiFiMulti" is not a type name - error in built in library example

Here is the websocket server example, in the platformio library search it is " WebSockets by Markus Sattler", unmodified fresh from the library, in arduino it works fine, but on platformio, it gives an error

variable “WiFiMulti” is not a type name

at line containing: WiFiMulti WiFiMulti;

i have no idea what the problem is or how to address such a problem

What’s your platformio.ini?

Not 100% certain, but declaring a variable with the same name as its type seems a little strange?

Similar to int int.
