OrientDB is the most versatile DBMS supporting Graph, Document, Reactive, Full-Text and Geospatial models in one Multi-Model product. OrientDB can run distributed (Multi-Master), supports SQL, ACID Transactions, Full-Text indexing and Reactive Queries.
Using Studio, got a NullPointerException in my SELECT execution caused by the use of an index that does not exist (a typo in my case).
The original error was obviously on my side, but I guess you would like to provide a better error message in such case.
The SQL looks like this one:
SELECT
FROM INDEX:ìndexthatdoesnotexist
The stacktrace is the following:
java.lang.NullPointerException
