Timeout error when calling a Skill Kit LLM from flow designer

anishmurali — Thu, 09 Apr 2026 07:58:09 GMT

Hi All,

I am calling a Skill kit LLM from Flow Designer using Execute Skill. The whole ticket record is passed from the workflow to the skill kit. When running the flow designer, I am receiving a timeout error as the time limit is set to 60 seconds.

However, the skill is running fine when testing it individually.

As an alternative, i tried to call the skill kit from "script includes" but that is not supported and the capability sys_id of the skill is not explicitly available.

How would i asynchronously call and run the LLM to send that response via email and bypass the timeout error?

Hi,

Can you tell me the instance version and the name of the skill set?

I faced similar issue with Agentic AI in the past. It works fine while testing, but it will never execute when it is triggered from a real scenario. Instead wait for the skill to execute and timeout after few minutes.

In my case, It was resolved after I upgrading the instance to Zurich.

You can try updating all the latest patches. If it is still not working then you can try upgrading instance and see whether issue is resolved.

Hi Palanikumar,

I am currently working on the Zurich 1 instance, and it is configured with a custom skill. Please let me know if you need any additional details or if there are specific aspects you’d like me to highlight.

Thanks and Regards,

Anish

I do not have the permissions to upgrade the patch, is there any alternative like making the flow designer wait until we get LLM output or identify its sys_id so that i can call from "Script Includes"?

Thanks you,

Anish

HI @anishmurali ,

ServiceNow releases lot of updates to NowAssist and it is always recommended to upgrade to latest Patch level. Even if you reach out to ServiceNow support, they'll ask you upgrade to latest patch.

Thank you,

Palani

The current patch is Zurich patch 7 now. I tried with Claude, OpenAI and Gemini as the Skill kit LLM.
However, the issue still persists.

Thank you,

Anish
