Virtual Agent Lite and VAFieldValidator

[benjaminmetzler]

Hi All,

I'm running into a problem with Virtual Agent Lite. When attempting to create a new incident, using the default ITSM `Report an Issue` topic provided out of the box, I get the message "I'm having technical issues and won't be able to continue this conversation." after it presents me with some possible support options related to my incident description. Looking in the logs, I see the below error, which seems to point to  the line:

var vaFieldValidator = new global.VAFieldValidator();

I think is trying to get the validators from the sys_cs_field_script_validator. At this point I'm stuck on why it is failing. Thoughts?

Thanks,

Ben

Of course, right after I posted this, I had a realization that the problem was the VAFieldValidator script include was the problem. Reviewing it, the include had been deactivated. Once I activated it, my problem was solved.
