创建新的FiwareService时，Orion CB中出现错误500

如何解决创建新的FiwareService时，Orion CB中出现错误500

我在MongoDB 4.0.5之上使用Fiware Orion CB版本2.1.0。一旦启动，一切似乎都可以正常工作，但是一段时间（几天）无问题地提取数据，现在，每次我尝试在新的fiwareservice中创建新实体时，OrionCB都会出现500错误（如果我尝试在现有的FS中创建相同的实体，则可以使用），而且我必须重新启动Mongo和Orion容器，才能使新的FS创建成功。

请求是：

curl --location --request POST 'context.infinitech.easier-ai.eu/v2/entities/' \
--header 'fiware-service: itscenterctag' \
--header 'fiware-servicepath: /vehicle' \
--header 'Authorization: Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' \
--header 'Content-Type: application/json' \

        },"test": {

                }
            }
        },"location": {

                ]
            },"name": {
            "type": "Text","value": "test","metadata": {}
        }
    }'

从MongoDB日志中，我得到：

更新：

仅在尝试创建新的FiwareService（通过在新的FS中创建新的实体）时发生。在已创建的FS中管理任何现有实体都可以正常工作。

更新二：（根据评论）

> use orion-foo
switched to db orion-foo
> db.entities.insert({x:1})
WriteResult({
        "nInserted" : 0,"writeError" : {
                "code" : 8,"errmsg" : "1: Operation not permitted"
        }
})

解决方法

考虑到UPDATEII中的信息，看来问题出在MongoDB实例本身，而不是Orion。我的意思是，mongo shell的失败表明数据库本身不允许创建新数据库（无论是谁创建的，要么是Orion，要么是mongo shell上的您，要么是连接到MongoDB的第三个应用程序）。

因此，建议您检查一下数据库设置。令人惊讶的是，根据该报告，它在一开始就可以工作，但一段时间后开始失败。也许某些带外操作（即管理过程）正在更改移动权限？
