Trying to return all fields in object

System.QueryException: unexpected token: '('

when I run the Invocable class at the parents = assignment

public with sharing class AuditReportBulkifyClass {



    @InvocableMethod(label='Collect Bulkified Records')

    public static List<List<hdone__AuditReport__c>> gatherRequests(Request requests) {

    public with sharing class Request {

        @InvocableVariable(label='Record ID' required=true)

        public Id recordId;



        @InvocableVariable(label='Object API Name' required=false)

There are some variable bindings that "normal" SOQL can resolve, but Dynamic SOQL cannot.

It's probably not a perfect rule, but if your variable binding includes a period/dot/full-stop like you have in parents.keySet(), then chances are that it won't work with Dynamic SOQL.

See the "Dynamic SOQL Considerations" section of the documentation on dynamic SOQL for a better idea of what, precisely, is and is not allowed.

The solution here is to store your parents.keySet() in a dedicated variable of type Set<Id> sometime prior to when you need it in your dynamic query. You could probably use String.format() somehow as well.
