Neo.TransientError.General.StackOverFlowError: There is not enough stack size to perform the current task. This is generally considered to be a database error, so please contact Neo4j support. You could try increasing the stack size: for example to set the stack size to 2M, add `dbms.jvm.additional=-Xss2M' to in the neo4j configuration (normally in 'conf/neo4j.conf' or, if you are using Neo4j Desktop, found through the user interface) or if you are running an embedded installation just add -Xss2M as command line flag
this error is not coming everytime , it is coming when i want to convert my data as json tree path .
could you please suggest me what is wrong with this .
I have added dbms.jvm.additional=-Xss2M in my conf file still getting same error.
Please share with us the code you're using to do the JSON conversion, and maybe a sample of the data in question.
Usually this sort of thing is going to be caused by unbounded recursion, where a function is calling itself and not terminating, adding to the stack until the stack overflows.
Hi david Thanks for your reply
Please find below cypher query
MATCH (a:ENTITY)<-[rels:ASSO*]-(b:ENTITY{BARCODE:'x'})
MATCH (a)<-[:Having]-(:ENTITY_TYPE{ENTITY_TYPE_NAME:abc'})
WITH collect(a) as nodes
With last(nodes) as m
MATCH (l)<-[:Having]-(:ENTITY_TYPE{ENTITY_TYPE_NAME:'abc'})
MATCH PATH = (m)<-[*]-(l)
with collect(PATH) as paths
call apoc.convert.toTree(paths) yield value return value
and data is like in tree format
in the top i have a node that is m in the query and this m have 6 child nodes and each child node have some childs .
Here Each node have same label and different properties . it has a unique property BARCODE
my requirement is if i give any barcode in query i should get whole graph in json as output
