Threadsafe issue

Hi,

 

I tried to export a Thing, but it did not work. Then I found this error in ErrorLog

Hi Sharon,

 

The problem is here. The Thing has a JSON property called State

 

"State":{"value":{"NextSend":{"className":"Date","empty":true,"sealed":false,"ids":[],"prototype":{"className":"Date","empty":true,"sealed":false

No Context associated with current Thread (through reference chain: org.mozilla.javascript.NativeDate["prototype"]->org.mozilla.javascript.NativeDate["ids"])

 

In a service, there is a code "me.State.NextSend = new Date()" => it should be stored as a JSON date value, but TW did not.

 

My Bests,

Hung Tran

Hi @htran-21.

 

Which version of ThingWorx are you running?  If 8.4, did you update \ThingworxPlatform\platform-settings.json to include the export statements?  Here is an article that provides an example of the platform-settings.json file containing the export statements.

 

Regards.

Hi Sharon,

 

That version is 7.4.1-b62. The export function was working on the Thing until a scheduler is scheduled to call it every 5 minutes. I guess there is a public property called "ids" in the Entity that stopped the XML serialization process, this property should be hidden from the XML serializer.

 

Anyway, I could not access the link, may you send the example of platform-settings.json. We also have a Thingworx server running 8.4

Hi @htran-21.

 

Here is an example of the platform-settings.json file for your ThingWorx 8.4 instance:

 

{
    "PersistenceProviderPackageConfigs": {
        "PostgresPersistenceProviderPackage": {
            "ConnectionInformation": {
                "jdbcUrl": "jdbc:postgresql://localhost:5432/thingworx",
                "password": "twadmin",
                "username": "twadmin"
            }
        }
    },
    "PlatformSettingsConfig": {
        "ExtensionPackageImportPolicy": {
            "importEnabled": true,
            "allowJarResources": true,
            "allowJavascriptResources": true,
            "allowCSSResources": true,
            "allowJSONResources": true,
            "allowWebAppResources": true,
            "allowEntities": true,
            "allowExtensibleEntities": true
        }
    }    
}

 

For the export issue on the 7.4.1 instance, is it just the one entity that fails to export?

 

Regards.

Hi Sharon,

 

Thank you for the example file.

 

Yes, it is the only entity "FileRepository" failed to export. It has worked after imported, and only failed to export when a Scheduler calls it. Remarks, the entity is still working, but unable to export.

Hi @htran-21.

 

We realize you marked your last post as the Accepted Solution but are confused.  You indicated that the problem was caused by ThingWorx not storing the JSON date value correctly.  How were you hoping to store this value?  String?  Number?

 

 

What was the solution that you actually found?  We want to be sure the community is understanding in case of further questions.

 

Regards.

Hi Sharon,

 

At this moment, JSON property would cause the issue if any DateTime value is stored,  I changed to store an equivalent number "dateValue.getTime()" of DateTime value instead. In my case, that is

 

me.State.NextSend = nextSend.getTime()

Hi @htran-21.

 

I'll have to research this one.  Does it work if you try to export in a different format?
