I was using the Nebula Graph database, and when I executed the following statement
match (o:HO_NEO4J_OBJECT_ID) - [r] - (a:HO_NEO4J_PERM) where r.hoid in [“1604715734952239104”] return id(o) as src, id(a) as dst | DELETE EDGE REFERENCES_OBJECTID_PERM $-.src → $-.dst
Error appeared like: https://discuss.nebula-graph.com.cn/uploads/default/original/2X/f/f1808aa86ce80984a8137f96d1dfe09082c89eae.png
