What is causing 'ReferenceError: "Authenticators" is not defined'?

[sclifford]

Hi,

Version: Thingworx 7.1.1

I want to get the ConfigurationTable of a custom Authenticator via a service of a Thing. I need to retrieve a configuration property.

To demonstrate, I am using the ThingworxMobileAuthorizationAuthenticator. The behaviour is the same as for the custom Authenticator.

Using Postman works fine, but when I try to code it using the Entities tab in the Service script, like so:

I get this error when I test it:

What does this mean?

Thank you,

Shane

Hi Shane Clifford​,

Attached is the export of Authenticators_ThingworxMobileTokenAuthenticator from my instance 7.2.3 and there is no configuration table for it.

Does your custom Authenticator have a Configuration Table?

Also, could please share more details about your custom Authenticator and how it works with postman.

Thanks,

Hi Ankit Gupta​,

Thanks for your reply. Copy and pasted the wrong Authenticator name

I meant ThingworxMobileAuthorizationAuthenticator, which has a configuration table named AuthenticatorConfiguration.

Here's the Postman request:

POST /Thingworx/Authenticators/ThingworxMobileAuthorizationAuthenticator/Services/GetConfigurationTable HTTP/1.1
Host: localhost:8081
appKey: <my_app_key>
Content-Type: application/json
Accept: application/json
Cache-Control: no-cache
Postman-Token: c4df65fa-f5f6-6cca-380c-dc578c00ab4a
{
    "tableName": "AuthenticatorConfiguration"
}
 

And here's the response:

{
  "dataShape": {
    "fieldDefinitions": {
      "tokenLifeTime": {
        "name": "tokenLifeTime",
        "description": "Token LifeTime",
        "baseType": "LONG",
        "ordinal": 0,
        "aspects": {}
      },
      "generateTokens": {
        "name": "generateTokens",
        "description": "Return generated tokens",
        "baseType": "BOOLEAN",
        "ordinal": 0,
        "aspects": {}
      }
    }
  },
  "rows": [
    {
      "tokenLifeTime": 2592000,
      "generateTokens": true
    }
  ]
}
 

Now, trying the following in a Service script:

var params = {
  tableName: "AuthenticatorConfiguration" /* STRING */
};
// result: INFOTABLE
var result = Authenticators["ThingworxMobileAuthorizationAuthenticator"].GetConfigurationTable(params);
 

Returns:

Error executing service

ReferenceError: "Authenticators" is not defined. (getConfigTable#6)

Details of our custom authenticator (which works successfully) isn't needed here, as the error received is precisely the same for the Thingworx Authenticator.

The custom authenticator stores a value in its configuration table during authorisation. Once logged into the instance, we need to a service that will read the property from our Authenticators configuration table.

Why does Thingworx Composer provide Authenticators under the Entities tab for coding a Script of a Service, and then throw a ReferenceError saying "Authenticators" is not defined... seems like a bug?

Thank you,

Shane
