Error in the query under "Terminal CREATE clauses"

The query provided under the terminal CREATE clauses [here](https://age.apache.org/age-manual/master/clauses/create.html#terminal-create-clauses) gives error instead of outputting '0 rows returned'

Upon executing the following query:
`SELECT *
FROM cypher('graph_name', $$
CREATE /* Create clause here, no following clause */
$$) as (a agtype);`

I get:

> ERROR: syntax error at end of input
LINE 4: $$) as (a agtype)
