ESC unable to show comment with unknown error

[Vincent Wong1]

Hi all, 

I was wondering anyone has encountered similar error before.

"'Encountered scriptable of unknown type Function in sn_std_tkt"

All of our employee center request detail page return such error when displaying request comments.

Thanks in advance,

Vincent Wong

Hi Vincent,

We've started experiencing this issue in one of our pre-production instances after upgrading to Washington Patch2 this weekend. It's only happening when we have an incognito browser, or after clearing cookies/site data from the browser cache.

We are using standard ticket pages to display tickets, and happens on all ticket types. The exact line of code that appears to be failing is in the server script for the Standard Ticket Conversation widget, line 133 (and the same line in a custom widget) "data.stream = $sp.getStream(data.table, data.sys_id);" - I've been investigating this morning when I came across your post and thought I'd share my findings so far.

Did you find a solution?

Additionally it seems to happen on a service portal survey widget that is embedded inside an order confirmation widget that we have - suggesting it's something to do with an embedded scoped widget.

Hi Doug,

My issue was resolved after requesting an instance health check and restart by ServiceNow support team.

It seems to be OOTB API issue.
