Url for call functions inside of a type seems not work

When I have an structure like:
```gql
type Query {
account(id: ID!): Account
}

type Account {
id: ID!
action(id: ID!): String
}
```
The route built is:
`/account/:id/`

When I call this endpoint:
`http://localhost:9229/rest/account/1/action/5`

I receive as a result:
`TypeError: ID cannot represent value: undefined`

No files or tests are named. Start by reproducing the provided nested GraphQL schema and REST request, then trace how the /account/:id/action/:id route maps arguments into the nested call. Done means the endpoint no longer produces the reported undefined ID error.
