The dijkstra function does not work as described, for example (SQLscript):
CREATE VERTEX TYPE V;
CREATE EDGE TYPE E;
CREATE PROPERTY E.distance LONG;
LET $src = (INSERT INTO V);
LET $dst = (INSERT INTO V);
CREATE EDGE E FROM $src TO $dst SET distance = 1;
CREATE EDGE E FROM $src TO $dst SET distance = 10;
LET $src = (SELECT FROM V LIMIT 1);
LET $dst = (SELECT FROM V LIMIT 1 SKIP 1);
SELECT dijkstra($src, $dst, 'distance') FROM V;
results in the error:
Error on command execution (PostCommandHandler): class com.arcadedb.graph.ImmutableVertex cannot be cast to class java.lang.String (com.arcadedb.graph.ImmutableVertex is in unnamed module of loader 'app'; java.lang.String is in module java.base of loader 'bootstrap')
Similarly, using instead:
LET $src = (SELECT FROM V LIMIT 1);
LET $dst = (SELECT FROM V LIMIT 1 SKIP 1);
SELECT dijkstra($src.@rid, $dst.@rid, 'distance') FROM V;
results in the error:
Error on command execution (PostCommandHandler): class com.arcadedb.database.RID cannot be cast to class java.lang.String (com.arcadedb.database.RID is in unnamed module of loader 'app'; java.lang.String is in module java.base of loader 'bootstrap')
So it seems the source and destination arguments for the dijkstra function are not parsed correctly.
