Hello hackers,
I've discovered an assertion failure produced with the following script:
CREATE TABLE v1 (id int primary key, t text);
CREATE TABLE v2 (id int primary key, t text);
CREATE TABLE e1_2 (id_1 int, id_2 int, t text);
CREATE PROPERTY GRAPH g1
VERTEX TABLES (v1, v2)
EDGE TABLES (
e1_2 key (id_1, id_2)
SOURCE KEY (id_1) REFERENCES v1 (id)
DESTINATION KEY (id_2) REFERENCES v2 (id)
);
SELECT count(*) FROM GRAPH_TABLE (g1 MATCH ()-> COLUMNS (1 AS one));
