AggregationFields and query filter how can in use together

Hi,

a!queryRecordType(
recordType: cons!YOUR_RECORD_TYPE,
fields: a!aggregationFields(
groupings: a!grouping(
field: "yourRecordTypeFields.fieldToGroup",
alias: "aliasForTheField"
)
),
filters: a!queryFilter(
field: "yourRecordTypeFields.fieldToFilter",
operator: "=",
value: "ValueToFilterBy"
),
pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 500)
)

That should not be an issue, you can try the below code and update your values and check.

a!queryRecordType(
  recordType: "RecordType",
  fields: a!aggregationFields(
    groupings: a!grouping(
      field: "recordFieldToAggregateHere",
      alias: "xyz"
    )
  ),
  filters: a!queryLogicalExpression(
    operator: "AND",
    filters: {
      a!queryFilter(
        field: "fieldToFilter",
        operator: "=",
        value: true,
        
      )
    },
    ignoreFiltersWithEmptyValues: true
  ),
  pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 100),
  fetchTotalCount: true,
  
),
cast(
  recordType,
  null
)
