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.
