apoc.refactor.mergeNodes while using apoc.periodic.iterate seems not working

[SimG92]

Hello,
in my database I have multiple nodes that have the same properties, so I want to merge all of these nodes into one. Those nodes are connected by the relationship "similar", so I use gds weakly connected component to find these communities, then I'm using the following code to merge those nodes in the same community while using the apoc.periodic.iterate

CALL apoc.periodic.iterate('
MATCH (n:Officer)
WITH n.community AS com, collect(n) AS nodicom
RETURN nodicom
','
CALL apoc.refactor.mergeNodes(nodicom,{
properties:"discard", mergeRels:true, preserveExistingSelfRels:false}) YIELD node
',{batchSize: 200, parallel: true})
YIELD batches, total
RETURN batches, total

I'm expecting that all nodes grouped by community will be merged but it does not working.
Using the following code I have a lot of communities with more than 1 node:

match (n) with n.community as com, count(n) as contacom return com, contacom order by contacom desc

if I use:

MATCH (n:Officer) where n.community=239389
WITH n.community AS com, collect(n) AS nodicom
CALL apoc.refactor.mergeNodes(nodicom,{
properties:"discard", mergeRels:true, preserveExistingSelfRels:false})
yield node
return count(*)

it works. 239389 is an example of id community
