a mapper like the ocs computer mapper is using config parameters from the ocs computer source.

example:
source.ocs.url is set
the mapper is trying to read the ocs.url to use it in some links.

are the config-contexts separated? can the mapper ask for source.ocs.url?
the ipinterface helper of ocs has the same problem with the categoryMap parameter that is now mapper.categoryMap

the error / log messages are not showing any indication about the prefix. they just say that categoryMap is missing and not thet mapper.categoryMap is missing.
