AggregationFields and query filter how can in use together

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
)

Thank you for your help.

I have another question。
I want to display other fields after aggregationFields. Is it possible?

oredersid"O1000"(Text)
customerid"0123456"(Text)
caseid"02"(Text)
caseID"02"(Text)　　←　　aggregationFields

No. You can either use a!aggregationFields() or recordFields in the fields parameter. Both do not work parallelly.
