This fixes an issue with a recent addition of a config file
check in c28ded36ef50cb80796c6bd946754abfb47ffa28.
Previously it was possible to supply a path as a string
to `configFile`. Now it will fail checking the config file
during evaluation of the module due to sandboxing.
A toggle to disable the check, more informative log messages
and handling for various configFile values are added.
