Cannot update project attribute via the REST API

Dear Community members,

I am encountering the following issue when try to update a project attribute using the REST API. I am using the end point "/attributeValues" and a most method.

I am passing the following body which - to me at least - seems correctly formatted and correspond to the example provided in the REST API documentation:

[

{

"value": true,

"attribute": {

"id": 1178,

"name": "EPO_Project_Formatted",

"displayName": "Formatted",

"resourceType": "PROJECT",

"type": "BOOLEAN"

},

"resource": { "id": 2094 }

}

]

 

After the Post is sent, I receive a response saying that method ran to completion but returned the following error:

{

"errors": [

{

"code": 500,

"type": "SERVER",

"message": "java.lang.NullPointerException"

}

]

}

 

When I check in the system log of the application, I can see that the following messages:

[2017-02-21 19:03:15,347] INFO http-apr-443-exec-8 com.sdl.lt.worldserver.service.permission.PermissionStageRouter: Checking permission for PermissionKey[resourceType=ATTRIBUTE_VALUE,permissionType=WRITE,auxPermission=CHANGE_PROJECT_ATTRIBUTES] [CHANGE_PROJECT_ATTRIBUTES]

Any idea why this is not working? Why is the resourceType "null" in the checking

Thanks in advance for your support.

  • Hi Laurent,

    can you please add the full stacktrace of the NullPointerException. You should see more lines in the logs.

    Thanks,
    Stefan.

  • You need to specify an aditional information: inside the attribute: readOnly and required.
    readOnly: It needs to be set to false in order for the change to work. If it is readOnly true in the system, but you give it readOnly=false, it will fail. But I suppose, this is not a readOnly attribute.
    required: also has to match the system setting.

    so something like so:
    [

    {

    "value": true,

    "attribute": {

    "id": 1178,

    "name": "EPO_Project_Formatted",

    "displayName": "Formatted",

    "resourceType": "PROJECT",

    "type": "BOOLEAN",
    "required":false,
    "readOnly":false


    },

    "resource": { "id": 2094 }

    }

    ]

    I know that this is not something you feel you should do. I agree with that and we'll remove this requirement in next releases.

    Thanks,
    Stefan.
