Specifying rows in slice shows no data

I want rows to be coming from Entity ID key values, so I set it in rows inside of slice object, and the rest of the fields I put in columns in slice. But when I load the table it is empty. I don't want any aggregations for now, just to show the values themselves.
Here is the code that I have:

processdata: function (d) {
var finaldata = [];
d.data.forEach(function (row) {
var currobj = {}
d.columns.forEach(function (col) {
var itemval = row[col.key];
currobj[col.label] = scil.Utils.isNumber(itemval) ? scil.Utils.parseNumber(itemval) : itemval;
})
finaldata.push(currobj);
});
return finaldata;
},
getcols: function (d) {
var finalcols = [];
d.columns.forEach(function (col) {
if (col.key != "compoundid") {
var currcol = {};
currcol.uniqueName = col.label;
currcol.showTotals = col.type == "float" ? true : false;
finalcols.push(currcol);
}
});
return finalcols;
},
getrows: function (d) {
var entitycol = d.columns.find(function (col) { return col.key == "compoundid" });
return [{ "uniqueName": entitycol.label }];
},
...
...
me.flexpivot = new Flexmonster({
container: divid,
componentFolder: "https://cdn.flexmonster.com/",
licenseKey: "...",
toolbar: true,
report: {
dataSource: {
data: me.processdata(d)
},
slice: {
columns: me.getcols(d),
rows: me.getrows(d)
}
}
});
 

So, rows array contains just a single object: { "uniqueName": "Entity ID" }. data is an array, objects of which have Entity ID as a key among other keys that are supposed to be columns. 
I suspect maybe measures need to be specified because when I add a column to values through UI, it starts showing rows, but the thing is that I don't need any aggregation to be done at the initial view and I don't see any aggregation of type, say, None.
