Python 为什么我的Cloud Run出现断管错误？

我在我的云计算运行中遇到了一个错误，在我的日志中，它说

管道断了

错误，当我检查代码中哪一行出错时，它在我的

db2.comit（）

上。我的云运行从6个月前开始一直运行良好，没有任何错误，但现在出现了这个错误

下面是日志中的详细信息

这是发生错误的代码行

    except Exception as e:  # noqa
        log = orm.LogPredictStatus(customer_id=customer_id, status_code=500, car_attribute=car.dict(), price=None, source='TEST', created_at=time_zone_jakarta)
        db2.add(log)
        db2.commit()
        raise HTTPException(
            status_code=500,
            detail=str(e),
        )

从我所看到的关于代码的少量信息来看，我猜测

log

中的某些内容不符合元素的预期。尝试调试

log

包含的内容。某个地方有一个空的缓冲区字段。感谢@ewong的响应，好的，它现在解决了，这是由我脚本上的插入方法引起的。
