Query not accepting named params passed from js-evaluator

Please refer to the following patch where the javascript runner is correctly passing named arguments of type udf.Value to context.OpenStatement() as per contract:

http://review.couchbase.org/c/eventing-ee/+/164329

• The call to OpenStatement does not return error which means query has been prepared and registered.

• However, when we call handle.NextDocument() query returns the following error:

Evaluator error Exceptions from JS code : run queryselect failed:\nException: Error: Error evaluating LIMIT - cause: No value for named parameter $boolval (near line 1, column 36).

This can also be reproduced via the following:

Create a new Javascript UDF with the following definition:

function queryselect(rowlimit) {

    var query = SELECT * from `travel-sample` LIMIT $rowlimit;

    var acc = [];

    for (const row of query) {

        acc.push(row);

    }

    return acc;

}

Create a function as follows:

create function math2queryselect(rowlimit) language javascript as "queryselect" at "math2";

And execute this statement:

EXECUTE FUNCTION math2queryselect(100);

Error:

No value for named parameter $rowlimit
