Hi,

Please provide "Salesforce Solution Architect" interview questions.

Thanks in advance.

I am trying to execute the following code for recalling an approval process an ends up getting the following error

execution of AfterUpdate caused by: System.DmlException: Process failed. First exception on row 0; first error: INVALID_OPERATION, Illegal transition type:

 Approval.ProcessWorkItemRequest pwr = new Approval.ProcessWorkItemRequest();
       
List<ProcessInstance> procins = new List<ProcessInstance>([select Id from ProcessInstance where Status = 'Pending' and TargetObjectId = :objectId]);
// Retrieve the process work instance id associated to the process instance
            List<ProcessInstanceWorkitem>  workitem = new List<ProcessInstanceWorkitem>([select Id from ProcessInstanceWorkitem where ProcessInstanceId = :procins[0].id]);

            if ((workitem != null) && (workitem.size() > 0))
            {
                pwr.SetComments(statusToUpdate);

                pwr.setWorkItemId(workitem[0].id);
                pwr.setAction('Remove');
            
               
                // Execute process request
                Approval.ProcessResult pr = Approval.process(pwr);

}
