s.getPreviousValue not working for other eVars than page name and channel

Question

Hi there,I do initialize the getPreviousValue-Plugin with Data Collection and then setting two eVars by using an additional rule, the Adobe Analytics extension and custom code looking like this:s.eVar18 = s.getPreviousValue(s.pageName,"gpv_pageName");
s.eVar19 = s.getPreviousValue(s.channel,"gpv_siteSection");Everything is working fine for this. Cookies are set, eVars are set as soon as cookies have a value.Now, I'm trying to add an additional line, looking like this:s.eVar17 = s.getPreviousValue(s.eVar2,"gpv_pageId");For this one, no cookie is built and therefore no eVar is set while eVar2 exists in the tracking calls.Can someone tell me why?

Hi @chrisludwig87

are you sure that eVar2 has been set by the time you are calling getPreviousValue?

What if you log it in the console? Do you see an actual value present?

_satellite.logger.debug(">>> this is eVar2", s.eVar2);

Hmm on the surface, this looks fine...

The only thing I can think of is your eVar2 being explicitly set? Or is it maintaining a value from a previous page (I assume not since it's called "page id", so I would expect that to be set for every page)

There should be no difference between maintaining the value of pageName or channel, or an eVar.... I even see eVars in the examples in the documentation.

Are you seeing any errors in your console?

I don't use this plugin, so to try and replicate I need to do some setup....
