Re: [I] [Bitnine Tech] - When it executes VLE(Variable Length Edge) query, why it occurs an error just the first try? [age]

   Thanks - this was a good debug experience.
   
   I think my key underlying question is about whether it’s possible to create 
a dangling edge via cypher queries alone?
   
   If not we would have to look at whether the vertex got deleted by some other 
route or something happened during creation.
   
   Also given that the request was for VLE for paths like this
   
   SELECT * FROM cypher('fishpond', $$
   MATCH (p:PropertyType)<-[edge:typeOf*0..]-(node:PropertyType)
   WHERE p.id = 'fish_weight_g'
   RETURN node, edge
   $$) as ( node agtype, edge agtype);
   
   I wonder that we went anywhere near edges that link to observations.
   While there are only a few 100 items in the property graph and a few 1000 in 
the feature graph there will be millions in the observation graph.
   
   Thanks Andrew

assumption that everything is set up correctly, meaning every edge that exists 
has vertices that exist. If it comes across issues, it just quits because it 
might be a data corruption issue.

just gives warning messages and continues.
