A question about schema functions：type()

[1260328762]

I have a problem when I use type() function with openCypher

This is my statement
match p=(a)-[e*..2]->(b) where id(a) == '123456' return p

I want to use type() function to exclude specified edge like this
match p=(a)-[e*..2]->(b) where id(a) == '123456' and type(e) != 'follow' return type(e)

But it didn't work, I used the following statement to see the result
match p=(a)-[e*..2]->(b) where id(a) == '123456' return type(e)
I found that it returned BAD_TYPE，this is the screenshot

Then I changed the statement, like this
match p=(a)-[e]->(b) where id(a) == '123456' return type(e)
And it worked, this is the screenshot

Is there something wrong with the way I use it or other reasons?

Good catch, it's because when it's multiple hops of edges, the e variable is a list.
