salesforce - FATAL_ERROR|System.DmlException：删除失败。第 0 行的第一个异常

Question

我有一个带有代码的批处理类

公共类 BatchDeleteEvents 实现 Database.Batchable、Database.Stateful、Database.AllowsCallouts {

private String query;
private String pageToken ;
private String CalendarId;
private String accessToken;
public BatchDeleteEvents(String CalendarId, String accessToken){

    this.query = 'Select Id, Name from Event__c'; // Query to get the CalendardID (Google ID)
this.CalendarId =CalendarId;
this.accessToken =accessToken;
}

public Database.Querylocator start(Database.BatchableContext BC){

    return Database.getQueryLocator(query);

}

public void execute(Database.BatchableContext BC, List<sObject> scope){
System.debug('Entered in delete Batch');
for(Event__c c : (List<Event__c>)scope)
 GCalendarUtil.doApiCall(null,'DELETE','https://www.googleapis.com/calendar/v3/calendars/'+CalendarId+'/events/'+c.name,accessToken);


    delete scope;
    }
public void finish(Database.BatchableContext BC){   
  for(CalendarSettings__c c: [Select Id, Name, CalendarId__c,CalendarQuery__c,FieldToDisplay__c from CalendarSettings__c])
     {  BatchPublicCampaignsToGoogle bjob = new BatchPublicCampaignsToGoogle(c.CalendarQuery__c,c.CalendarId__c,c.FieldToDisplay__c);
        Database.executeBatch(bjob,9); // This is set to process 9 records, allowing 1 extra callout for refresh token in case needed.
    }
    }

    }

我用 9 批运行它

BatchDeleteEvents del = new BatchDeleteEvents(c.CalendarId__c,accessToken); Database.executeBatch(del,9);

我面临错误

FATAL_ERROR|System.DmlException: Delete failed. First exception on row 0 with id a0290000007fCbEAAU; first error: ENTITY_IS_DELETED, entity is deleted: []

Class.BatchDeleteEvents.execute: line 26, column 1

我没有使用删除命令的地方为什么我面临这个错误任何人请帮助？

Answer 1

也许您删除 for 循环中的所有范围，将其更改为

for(Event__c c : (List<Event__c>)scope){
  GCalendarUtil.doApiCall(null,'DELETE','https://www.googleapis.com/calendar/v3/calendars/'+Cal   endarId+'/events/'+c.name,accessToken);

 }
 delete scope;
