The recursive query has more than one recursive part. Support for that was added in 3.34.0 released 2020-12-01. <https://sqlite.org/releaselog/3_34_0.html> item 2. If you want to use an earlier version of SQLite3 that can only use a single recursive part, then you have to remove the *isOneWay* flag from the table, remove the index, remove the last part of the recursive query, and add an extra row to the edges table for the edge from 3 to 2.
