configParser issue when applying datalayer to different site than WeRetail about aem-datalayer HOT 3 OPEN

The issue seems to be present when the page is within a folder structure - which is the case for all of the websites in the project I'm working on. When there are at least two outer folders (not one weirdly enough) the issue arises. This is an example of the bad json string that can't be parsed:

"{"path":"/content/testfolder/testfolder2/root/jcr:content/par_fullcolumn/brandedcontainer-B4",
"slingPath":"/content/testfolder/testfolder2/root/jcr:content/par_fullcolumn/brandedcontainer-B4.html",
"dialog":"/apps/branded/components/content/brandedcontainer/cq:dialog",
"dialogLoadingMode":"auto",
"dialogLayout":"auto",
"dialogSrc":"/mnt/override/apps/branded/components/content/brandedcontain<!--cq{"

Looks like a code-comment might have something to do with the issue? The string always stops abrubptly at <!--cq{ and obviously lacks some closing parentheses.

Also, the issue appears in edit mode and not in published mode. There is a chance that our page components are at fault, but it's hard to say at this point.

Also on the backend-side this error appears when we experience the issue:

GET /content/subpath2.html HTTP/1.1] com.day.cq.wcm.core.impl.WCMDeveloperModeFilter Error during include of SlingRequestPathInfo: 
path='/content/subpath2/jcr:content/par_fullcolumn/brandedcontainer-B4/par', selectorString='null', extension='html', suffix='null'
org.apache.sling.api.scripting.ScriptEvaluationException: java.lang.StackOverflowError

"subpath2" is the page where the datalayer configuration is added.
