Script Include Process Time

[ChezAndrewI0898]

I have a script include which utilizes Rest Message.

Sometimes it stops running at the middle of execution without an error.

Is there a maximum process time or maximum json reponse limit ServiceNow can handle?

Thank you.

may be the response is huge or the time it takes to get response is huge

what's your debugging and findings?

Hello @ChezAndrewI0898 

The issue occurs because ServiceNow enforces a 30‑second max timeout for outbound REST calls when the property glide.http.outbound.max_timeout.enabled is true.
To allow longer REST processing, ServiceNow recommends:

1. Set glide.http.outbound.max_timeout.enabled = false
2. Then use waitForResponse() to specify a higher timeout for that specific REST call.

Hello @ChezAndrewI0898 ,

Try using executeAsync() instead of execute().

Hi @ChezAndrewI0898,

Yes, ServiceNow does enforce execution and timeout limits for outbound REST calls, and what you’re seeing is usually related to one of those rather than a strict JSON size limit.

Or there is no single documented “maximum JSON response size” for RESTMessageV2, but very large responses can indirectly cause the following:

i. Timeouts

ii. Memory pressure

iii. Slow parsing

iv. Transaction cancellation
