UI - ConceptMap not rendering

[ralych]

Some bigger and complexer ConceptMaps seems not to render:
i.e. this call works fine
but
i.e. this call returns an Internal Server Error (See log below).
curl request
curl https://tx-dev.raly.ch/r4/ConceptMap?url=http://fhir.ch/ig/ch-vacd/ConceptMap/ch-vacd-vaccines-targetdiseases-cm
works fine

Log shows:
