Export Data Store Entity to Excel Smart Service Filters

Hi, 

I am working on exporting a record grid to excel. I am getting an error message while using Export Data Store Entity to Excel Smart Service. 

Filters field must be of type QueryFilter or LogicalExpression (APNX-1-4505-019).  I am using a script task to get the values and passing into the filter node input. 

What could be the problem here? Can anyone help me with it? Thanks

a!queryLogicalExpression(
  operator: "AND",
  filters: {
    a!queryFilter(
      field: "partNumber",
      operator: "includes",
      value: pv!partNumberFilter
    ),
    a!queryFilter(
      field: "supplierId",
      operator: "=",
      value: pv!supplierFilter
    ),
    a!queryFilter(
      field: "manufacturerId",
      operator: "=",
      value: pv!manufacturerFilter
    )
  },
  ignoreFiltersWithEmptyValues: true
)
