Receiving error "the undefined value has no properties" calling script include from Business Rule

Hi Guys, i have imported psl that's a JavaScript domain name parser based on the Public Suffix List in a Script Include.

The script include testing works correctly in a fix script but i receive "the undefined value has no properties" when i try to call it into a Business Rule.

Script Include pslv182 is attached, Application GLOBAL Accessible from "ALL APPLICATION SCOPES"

===========FIX SCRIPT===================

gs.include('pslv182');
var parsed = psl.parse('titolari.info.legacyconstructionok.com');
gs.print(parsed.tld); // 'com'
gs.print(parsed.sld); // 'google'
gs.print(parsed.domain); // 'google.com'
gs.print(parsed.subdomain); // null

========================================

And it'works GREAT!

Script: 

Completed: Event Management - process events in 0:00:00.022, next occurrence is 18/02/2021 00:22:31
Completed: Pick up throttled integration process in 0:00:00.024, next occurrence is 18/02/2021 00:22:28
isValid(): entered for connection 15 (connpid=3677415)
Completed: Service Mapping - check for changes in t in 0:00:00.008, next occurrence is 18/02/2021 00:22:31
isValid(): Connection 15 is valid (connpid=3677415)
Completed: Error Manager - retry discovery on all p in 0:00:00.008, next occurrence is 18/02/2021 00:23:26
*** Script: com
*** Script: legacyconstructionok
*** Script: legacyconstructionok.com
*** Script: titolari.info
[0:00:00.397] Total Time

 

By the way it stucks in a Business Rule (Application Security Incident Response)

================Business Rule================

(function executeRule(current, previous /*null when async*/) {
 
   var gr = new global.pslv182();  
   var parsed = gr.psl.parse('titolari.info.legacyconstructionok.com');
   gs.info('CHECK PKR TLD: '+parsed.tld); // 'com'
   gs.info('CHECK PKR SLD: '+parsed.sld); // 'google'
   gs.info('CHECK PKR DOMAIN: '+parsed.domain); // 'google.com'
    
    
})(current, previous);

===========================================

============ERROR LOG=====================

Any suggestion??

Many thanks!

1 ACCEPTED SOLUTION

In the fix script example, you loaded the library like this:

gs.include('pslv182');

Whereas in your business rule you are trying to instantiate it using the keyword new, and it seems it cannot work that way.

Have you tried the gs.include syntax in the business rule?

Hi Slava, thanks for you reply! I have made a try and this is logging result...

 

BTW the value in gr is "undefined"

Hi,

can you try to add try catch block to know the exception

Also can you try to call it from some other custom scope from background scripts

Also what is psl ?

you are trying to call the parse() function but what is the prefix psl

(function executeRule(current, previous /*null when async*/) {

    try{
        var gr = new global.pslv182();  
        var parsed = gr.psl.parse('titolari.info.legacyconstructionok.com');
        gs.info('CHECK PKR TLD: '+parsed.tld); // 'com'
        gs.info('CHECK PKR SLD: '+parsed.sld); // 'google'
        gs.info('CHECK PKR DOMAIN: '+parsed.domain); // 'google.com'
    }
    catch(ex){
        gs.info('Exception'+ex);
    }


})(current, previous);

This is logging...

 

BTW psl is what i have called into fix scritp to testing:

==========fix script==============

gs.include('pslv182');

var parsed = psl.parse('titolari.info.legacyconstructionok.com');
gs.print(parsed.tld); // 'com'
gs.print(parsed.sld); // 'google'
gs.print(parsed.domain); // 'google.com'
gs.print(parsed.subdomain); // null

================================

 

Did you see the Script include attached? It's a library included into SI.

 

Hi,

I tried pasting it in the script include but since it has more lines of code page became unresponsive

can you share the screenshot of the script include along with highlighting that parse function
