Add new property to existing node from CSV

[vence_andersen1]

Hi, 

I have nodes on my neo4j, now I am trying to add a property to the existing nodes from a CSV file. I used the query

load csv with headers from "file:///testfile.csv" as line
FOREACH(ignoreMe IN CASE WHEN line.alpha is not null THEN [1] ELSE [] END|
merge (Alphas{Name : line.alpha})
on match set n.Id = line.Id
)

But this is giving me an error 

Don't know how to treat that as a boolean: String("asd123")

 I got the above query from here . Thanks in advance.
