Cannot compile :c

[SliceN64]

I cannot compile because

Compilation error: call of overloaded 'getParam(int)' is ambiguous

Can anyone help me?

This is the full error:

I get the same when trying to build the current codebase according to the Wiki.

That's exactly what is happening to me as well.

"c:\Users\danie\Documents\Arduino\libraries\ESP_Async_WebServer\src/ESPAsyncWebServer.h"
Try to find newer (or older) versions of the "ESPAsyncWebServer" Arduino library.
The code you're trying to build might have been updated, and require the 3rd party libraries to also be updated. Arduino doesn't make this very easy.
(Note: In case you're trying to build older GBSC code, then you might have a too new version of the library. In that case, you'd need to downgrade it.)

Don't update your packages in the IDE. Just download the repository linked in the wiki. I had the same error as I updated my packages from the IDE, but rolling it back and manually extracting the zip from the link to the code in the wiki allows it to compile.
