EPANET getdata error missing argument

Hi, everyone!

I'm trying to learn epanet by doing some of the example I found on the Internet. But when I tried this line

fprintf('nodes = %d\n',getdata('EN_NODECOUNT'))

I get the error: Check for incorrect argument data type or missing argument in call to function 'getdata'. I assume it's because the api call changed in epanet or something. Same with 'setdata'. Does anyone know where to find which functions do they change to? I checked epanet github but couldn't find it there. Thank you in advance!

I am facing the same issue. Have you find the solution?

setdata('EN_DIAMETER', D);

Thanks in advance
