Saiku Hierarchize function not returning expected cellset - rest

Question

Can someone explain me why this mdx query executed against Saiku rest api does not return expected cellset? This query is executed as mdx type ThinQuery.
SELECT
{
[Location.CountryHierarchy].[Croatia]
,[Location.CountryHierarchy].[Serbia]
} ON COLUMNS
,Hierarchize
(
Union
(
{
[Product.ProductHierarchy].[Drinks]
,[Product.ProductHierarchy].[Food]
}
,[Product.ProductHierarchy].[Drinks].Children
)
) ON ROWS
FROM [Sales cube];
Expected output(tested with jpivot, pivot4j and Pentaho SchemaWorkbench/MDX explorer)
ExpectedResult
Actual result rendered on Android OLAP client am working on - just to be sure I also checked returned json from saiku server and really cells are missing.
Actual result

Answer 1

If you are executing using the execute endpoint and passing MDX or a Query Model in, you need to play with the properties section, try this:
"properties": {
"saiku.olap.query.automatic_execution": true,
"saiku.olap.query.nonempty": true,
"saiku.olap.query.nonempty.rows": true,
"saiku.olap.query.nonempty.columns": true,
"saiku.ui.render.mode": "table",
"saiku.olap.query.filter": true,
"saiku.olap.result.formatter": "flat",
"org.saiku.query.explain": true,
"org.saiku.connection.scenario": false,
"saiku.olap.query.drillthrough": true
}

Maybe try adding in the [ALL] member for Food to force the issue?
This was my AdvWrks mock-up:
SELECT
{
[Product].[Category].&[4]
,[Product].[Category].&[1]
} ON 0
,Hierarchize
(
Union
(
{
[Customer].[Customer Geography].[Country].&[Australia]
,[Customer].[Customer Geography].[Country].&[Canada]
}
,{
[Customer].[Customer Geography].[Country].&[Australia].Children
,[Customer].[Customer Geography].[Country].&[Canada].[All]
}
)
) ON 1
FROM [Adventure Works]
WHERE
[Measures].[Internet Sales Amount];
So in your scenario:
SELECT
{
[Location.CountryHierarchy].[Croatia]
,[Location.CountryHierarchy].[Serbia]
} ON COLUMNS
,Hierarchize
(
{
[Product.ProductHierarchy].[Drinks]
,[Product.ProductHierarchy].[Food]
,[Product.ProductHierarchy].[Drinks].Children
}
) ON ROWS
FROM [Sales cube];
