Error feature of form type

MPapini91 commented 3 months ago

Sembra esserci un problema nel recupero delle opzioni per le feature di tipo Form, un errore 500 del tipo:

Sembra non sia passato il valore della stringa di filtro

@andreabellandi il problema sembra essere a livello di LexO, anche se ovviamente saranno necessarie delle verifiche coordinate. In particolare sembra non riuscire a trovare risultati anche per forme esatte esistenti

Il problema era causato dalla non rigenerazione degli indici di Lucene dopo l'aggiornamento del repo in graphdb. Rimangono, comunque, da gestire le situazioni per le quali si genera una eccezioni nella query SPARQL (come nel caso di problemi negli indici) altrimenti al frontend arriva un error 500 che non sa gestire.
