I am getting this error message when I try to complete my sketch. Can anyone help me?

Error compiling for board Arduino Uno.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I’m guessing the unnamed file ‘__________’ doesn’t exist ?
Im not sure, because in my code and in the libraries folder the file is present. So im actually clueless about this error.

#include
The filename should immediate;y follow the

Post your full sketch
It might be an error due to wrong preprocessing done by the IDE
Hi, @Maxdfalcon
Welcome to the forum.
See also FAQ - Arduino Forum for general rules on forum behaviour and etiquette.
Hello,
Welcome to the Arduino Forum.
This guide explains how to get the best out of this forum. Please read and follow the instructions below.
Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is fru…
It will show you how to post code in a scrolling frame.
Thanks.. Tom...

what board are you really using?
I see you include
which are ESP related libraries but you are compiling for a UNO
sorry for the late response, I am using an esp32. I will try to change my board setting on the IDE. Thanks!
