Error after Rule fired

[Luca_Lattarini]

Hello everyone,

I am getting this error after every rule is fired? Any idea? Thanks

Hi @Luca_Lattarini , this looks like an error in some custom code (or erroneous extension).

In particular it looks like someone is referencing a promise that has never declared (e.g. promiseEG.then(()=>...., by default promiseEG would be treated as a null object if not declared properly and the interpreter would be looking for a property of the object called "then").

From the screenshot, it would be within whichever rule usually fires just after the "All Pages - User UUID - Authenticated -10" rule. It's worth noting that whatever rule is using promises, you will not get the desired functionality on Internet Explorer since it doesn't support Promise.prototype.then().

@ jantzen_belliston-Adobe I still have this issue.

@Luca_Lattarini , the timing of this error just makes it appear that it is coming from a rule. If you aren't using any custom code in a rule, it is likely coming from the use of an extension within a rule. E.g., if you are using a Data Layer extension, it could be that you are referencing an undefined object. Start by narrowing down the search to just rules with custom code and/or those that are interacting with a data layer.
