Processing fails due to issues with the triple-list

[jexp]

all my files are failing now in prod, please fix

we should have a validation / filtering for start and end-nodes
otherwise we need to fiilter out the triples that don't match but this sounds rather like a general problem

but it shouldn't happen in the first place given that the triples come only from the UI config and the node-lists should be the distinct sets of start and end nodes types
