Thank you Andy! I tried both variants:

WITH head($nodes) as nodes
CALL apoc.refactor.mergeNodes(nodes,{
  properties:"combine",
  mergeRels:true
}) YIELD node
RETURN node;

and

Match (n) where id(n) in $nodes
with collect(n) as nodes
CALL apoc.refactor.mergeNodes(nodes,{
  properties:"combine",
  mergeRels:true
}) YIELD node
RETURN node;

Unfortunately, it produced the same error message.
