SimpleWebServerWiFi compilation error

Official Hardware Classic UNO WiFi Rev2
1

Hi guys
I was trying out some official sketches from the Arduino IDE examples:
File -> Examples -> WiFiNINA -> SimpleWebServerWiFi.ino
for creating a webserver on my Arduino uno wifi rev 2,
when I encountered a compilation error...
On the net I can’t find any suggestions about this error:

C:\Users\PC\AppData\Local\Arduino15\packages\arduino\hardware\megaavr\1.8.8\cores\arduino\main.cpp: In function 'main':
C:\Users\PC\AppData\Local\Arduino15\packages\arduino\hardware\megaavr\1.8.8\cores\arduino/api/Stream.h:50:7: warning: 'MEM[(struct Stream &)&client]._startMillis' may be used uninitialized in this function [-Wmaybe-uninitialized]
class Stream : public Print

They look to me as though they are warnings rather than errors

Thank you for your kind answer and your precious time.
The problem was that I could not load the sketch.
Now despite everything is loaded and seems to work.
These Warnings can be corrected easily ?
