Power M Query from Azure Portal shows zero rows in table when put in PowerBI

Hi, here is the code with the server names changed to *********. This is exported as a PowerBI M Query and pastes into Advanced Editor of PowerBI. As above it runs fine but returns zero rows in the table.

let lastmonthNumber = getmonth(datetime(now)) - 1;
let lastmonth = iff(lastmonthNumber == 0, 12, lastmonthNumber);
let year = getyear(datetime(now)) - iff(lastmonth == 12, 1, 0);
let dateStart = make_datetime(year, lastmonth, 01);
