I have a graph where the vertices are labeled as "Person" and "Film":
```
v
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
{"id": 844424930131971, "label": "Person", "properties": {"name": "Sean",
"bornIn": "Santa Monica", "surname": "Astin", "occupation": "Actor"}}::vertex
{"id": 844424930131970, "label": "Person", "properties": {"name": "Wil",
"bornIn": "Burbank", "surname": "Wheaton", "occupation": "Actor"}}::vertex
{"id": 844424930131969, "label": "Person", "properties": {"name": "Rob",
"bornIn": "New York", "surname": "Reiner", "occupation": "Actor"}}::vertex
{"id": 844424930131972, "label": "Person", "properties": {"name": "Billy",
"bornIn": "Glasgow", "surname": "Boyd", "occupation": "Actor"}}::vertex
{"id": 1125899906842625, "label": "Film", "properties": {"title": "The Lord
of the Rings: The Fellowship of the Ring", "releaseDate": "2001-12-10",
"runningTimeMin": 178}}::vertex
{"id": 1125899906842626, "label": "Film", "properties": {"title": "The
Goonies", "releaseDate": "1985-06-07", "runningTimeMin": 114}}::vertex
{"id": 1125899906842627, "label": "Film", "properties": {"title": "Stand By
Me", "releaseDate": "1986-08-22", "runningTimeMin": 89}}::vertex
```
And the edges are as follows: (start_id is related to a vertex labeled as
"Person" and the end_id to a "Film")
```

```
When I type the following query, all the names of the vertices with label
"Person" are shown:
```sql
SELECT * FROM cypher('demo', $$
MATCH (p:Person)-[e]-(f:Film)
RETURN p.name $$) as (name agtype);
```
```
name
---------
"Rob"
"Billy"
"Sean"
"Sean"
"Wil"
(5 rows)
```
But when I do the same thing with an edge, it returns nothing, just blank
rows:
```sql
SELECT * FROM cypher('demo', $$
MATCH (p:Person)-[e:ACTED_IN]-(f:Film)
RETURN e.start_id $$) as (start_id agtype);
```
```
start_id
----------
(4 rows)
```
Why does it show only blank spaces and not the respective id?
