Script Include Instantiation in Business Rule Returns Error "[object Object] is not a function."

[Corey Farmer]

Hello,

I have a Business Rule created on a custom table configured to trigger off of two conditions:

  1. Field 'u_status' is 'Refresh'

or 

  2. Field 'u_last_webhook_dt' changes

Condition 1 is triggered from a UI Action button labeled 'Refresh', while Condition 2 is triggered from a Scripted REST API script.

When triggering using the 'Refresh' UI Action the Business Rule errors when attempting to instantiate my global script include; however, when triggering from the Scripted REST API or from a background script the Business Rule instantiates the object successfully and completes without error.  

Ultimately, my question is: why am I getting the `[object Object] is not a function` error when instantiating the Script Include through the UI Action, but not getting the error when using the Scripted REST API or background script?

Things I have verified:

• All scripts are in `Global` scope
• 'Isolate Script' is turned off for all relevant scripts
• Verified the user clicking the UI Action has all necessary roles 

The Business Rule code and error thrown are shown below:

try {
    var DealHubCPQHelper	= new global.DealHubCPQHelper( ),     // <-- ERROR THROWN HERE
	quotedetails			= DealHubCPQHelper.getDealHubQuoteDetails( current ),
	nil;

} catch ( err ) {
	err.func = "Business Rule: DealHub API Get Quote Details";
	gs.error( [ err.message, JSON.stringify( err ) ].join( ), "DealHubCPQ" );
}

Error Message:

[object Object] is not a function.,
{"message":"[object Object] is not a function.","fileName":"sys_script.609271651b0d42509c9b0e12604bcb93.script","sourceName":"sys_script.609271651b0d42509c9b0e12604bcb93.script","lineNumber":9,"name":"TypeError","stack":"\tat sys_script.609271651b0d42509c9b0e12604bcb93.script:9 (executeRule)\n\tat sys_script.609271651b0d42509c9b0e12604bcb93.script:40\n\tat sys_script_include.00087ee91b74c61062638556cc4bcbc4.script:333 (cleanseGlideRecord)\n\tat sys_script_include.00087ee91b74c61062638556cc4bcbc4.script:307\n\tat sys_ui_action.c3b9e62d1bcd42509c9b0e12604bcb75.script:24\n","rhinoException":{},"func":"Business Rule: DealHub API Get Quote Details"}

 So, starting from the bottom of the stack, we see the 'sys_ui_action' execute, followed by the script call within the UI Action to 'cleanseGlideRecord' which completes successfully and provides the record `.update()` function which triggers the Business Rule 'DealHub API Get Quote Details' to execute.

The UI Action script is as follows:

function getQuoteDetails ( ) {
	var answer 	= confirm( "Are you sure you want to refresh details using the DealHub API Engine?\n\nThis will clear, retrieve, and parse new quote data from DealHub for the selected record(s)."),
		nil;

	// Interact with the form button using g_form to allow use of confirm dialog
	if ( answer == true )
		gsftSubmit( null, g_form.getFormElement( ), 'dealhub_get_detail' );
	else 
		return false;
}

try { 
	if ( typeof window == "undefined" ) {

		current.setValue( "u_status", 					"Refresh" );
		
		var DealHubCPQHelper	= new global.DealHubCPQHelper( ),
			GrDealHubCPQQuote	= DealHubCPQHelper.cleanseQuoteDetails( null, current ),
			nil; 	

		action.setRedirectURL( current );		
	}
} catch ( err ) {
	err.func = "UI Action.Refresh";
	gs.error( JSON.stringify( [ err, err.message ].join( ) ), "DealHubCPQ" );
}

Depends on what you have in the script include DealHubCPQHelper().

Are you doing something in the initialize function of this Script include which may be causing the error.

Hi @SanjivMeher , 

Thanks for your interest. 

I too had the thought that the Script Include must be wrong somehow and compiling wrong; however, remember, the same Script Include works if I execute the call through the Scripted REST API.  Below is my `initialize` function within `DealHubCPQHelper()`.  So, no - I'm not changing anything or returning anything that should play a factor here.  I have even removed all the contents of `initialize` but receive the same error.  I have also tried removing all other methods within the Script Include (besides the initialize function) but get the same error.  It ultimately, doesn't seem related to the Script Include structure.

 initialize: function( current ) {
	if ( current ) {
		this.current = current;
	}
},

[SanjivMeher]

You shouldn't need to do this. You can leave the initialize function empty. I would start with fixing this.

 initialize: function( current ) {
	if ( current ) {
		this.current = current;
	}

Hi @SanjivMeher 

I mentioned I have already attempted this in my last post "I have even removed all the contents of `initialize` but receive the same error." 

While the initialize function contents are not necessary here, they are useful in other invocations of the main class in Business Rules where I do pass in 'current' as an object to perform actions against.

In either case: I have removed the contents per your recommendation for testing, and the same error and experience persists.  Thank you again for your assistance.
