Escape characters in String in cypher statement

[nitinjkt]

Dear Team,

I am facing some challenges while trying to call multiple apoc procedure within one another.

call apoc.custom.asProcedure('RIL_ODU_PATH_TERMINATION_V1',
'call apoc.bolt.execute("bolt://user:password@10.144.97.90:7070",
"match (a:inventoryObjects{type : $param11})-[r:INSTANCE_OF]->(c:classes{name:'gPath'})
where ((a.name = $param22 and $param22 is not null) or (1=1 and $param22 is null))
with a
optional match (b:inventoryObjects{site_inst_id : a.a_side_site_id})-[r:INSTANCE_OF]->(c:classes{name : 'gFacility'})
with a,b
optional match (d:inventoryObjects{site_inst_id : a.z_side_site_id})-[r:INSTANCE_OF]->(c:classes{name : 'gFacility'})
with a,b,d

while i am executing above statement, custom procedure is created but when i executed this procedure by using statement
call custom.RIL_ODU_PATH_TERMINATION_V1('ODU',null)

Its showing error as

I understnad its string concatenation or escaping character but not able to resolve it.

It would be grateful If any one can help to resolve this issue.
