Hello,
can someone tell me what is wrong with this trigger:
CALL apoc.trigger.add('updateLabels',"UNWIND apoc.trigger.nodesByLabel($assignedLabels,'VEGETABLE') AS o
with o.node as og
MATCH (og)<-[:TRANSLATED]-(n:FOOD)
WHERE og:FOOD AND og:ENG
SET n:VEGETABLE", {phase:'before'})
After execution of "MATCH (n:FOOD:ENG) SET n:VEGETABLE RETURN n" I got this error:
Neo.ClientError.Transaction.TransactionHookFailed
Error executing triggers {updateLabels=Unable to complete transaction.}
Here are logs from neo4j.log:
2021-01-02 23:52:19.053+0000 WARN [neo4j] Error executing trigger updateLabels in phase before Unable to complete transaction.
