# Diagnosis
Problem: schema nodes have no properties. Normally it has expected keys with blank for values.
{ "type": "Ideals", "in": [ 0, 2, 3 ], "out": [ 9, 10, 11 ], "props": {} },
Problem: schema relations did not have recognizable type names. Maybe the extra colons tricked the parser into doing the wrong thing.
{ "type": "", "from": 1, "to": 0, "props": { "PRIORITIZES": "Ideals" } },
