odata v2 sorting not working (Java v1 backend service)

[WFlats]

I want to find the earliest start of a task entity at a certain location with an odata v2 read operation.
This is the code

oModel.read("/Tasks", {
filters: [new Filter("location_ID", FilterOperator.EQ, sLocationID)],
sorter: [new Sorter("actualStart", false)],
urlParameters: {
$top: 100 // revisit
},
success: function (oData) {...

I usually only have to use "$top: 1" as this first entity contains the earliest task.

But I realised that the data is not sorted.

When I look at the HTTP request then the payload doesn't contain any "orderBy" statement.

SAP support told me to ask a question here as it is custom code.

Can anyone see an error in my code? I used such read operations with a sorter many times and can't see a mistake.

Hello,

Replace the parameter name with ‘sorters’ instead of ‘sorter’..

Also make sure your alias points to the correct class..

Subhajit provided the corect answer in his comment. Thanks very much!

Not sure how many times I checked the code but couldn't see it...
