'Function getGlideObject is not allowed' error message on Business Rule

[matthew_hughes]

I'm wanting to the update the following field on a request based on the time a request is created:

I'm wanting to update the value via the following Business Rule:

However, when I create a new request and save it, I get the following error message and the field is not populating:

I was just wondering if somebody could explain why the error message is occurring and what I need to do prevent it from re-occurring.

Hi @matthew_hughes 

Can you use different condition in "When to run" section just for testing and check if error message is there ??

I doubt it's because of condition.
