Why is the oetl throwing above exception. I am trying to create an edge
between 2 imported classes from mysql. Everything seems to be ok. Here is
my oetl
{
"config": {
"log": "debug"
},
"extractor" : {
"jdbc": { "driver": "com.mysql.jdbc.Driver",
"url": "jdbc:mysql://localhost/dss",
"userName": "root",
"userPassword": "welcome101",
"query": "select * from activity_log" }
},
"transformers" : [
{ "edge": { "class": "activity_entity_details", "direction" : "out",
"joinFieldName": "entityType",
"lookup":"entity_tree.id", "unresolvedLinkAction":"WARNING"} }
],
"loader" : {
"orientdb": {
"dbURL": "plocal:../databases/dss",
"dbAutoCreate": true,
"dbType": "graph"
}
}
The edges are not being created. Any clues why it is throwing a npe?
