Server JavaScript error Cannot read property "answer" from null

[Dave_p]

Hi,

I am in a confusing situation. I have this catalog item. I have deactivated all the catalog client scripts. Still, I am getting this error 'Server JavaScript error Cannot read property "answer" from null'. Kindly help.

I have highlighted in one of the screenshots. This happens only when I click on this (yellow high lighted). At the form submission level its all good.

Regards

Suman P.

find out and verify return, sysparm parameters, client callable is not missing in the script include. 

You call also verify the client script In the widget client controller it might returning the NULL.

Hello @Dave_p ,

The error indicates an issue with processing the Tabs of the Standard Ticket Configuration for Requested Items, specifically the advanced script for making them visible. Please set Advanced to "false" for all the tabs where it is currently "true" and check if this makes the error go away. If it does then debug the Visible script.

Regards,

Robert

@Dave_p ,

Please check the syslog table for any other logs related to the time when the issue is replicated.  You may see some scripts (script includes) that are in an encoded or corrupted test, rather than readable script.  The plugin  of that script will need to be reparied for your particular instance.
