RxResult's summary method is not there

I’m trying to run a simple delete query using the latest reactive session API with neo4j-driver@4.0.1 using node 12.12.0.

Example of the query I am trying to run

MATCH (n)
DETACH DELETE n

The way I’m running this is the following. I’m getting an RxSession from the driver

rxSession.writeTransaction(trx =>
  trx
    .run(statement)
    .summary() // fails on this line
    .pipe(
       map(result => ({ message: `Deleted ${result.counters.updates().nodesDeleted || 0} record(s)` })),
       tap(mappedResult => console.log(mappedResult.message)),
    ),
)

The exported types from result-rx.d.ts seem to indicate there is a summary() which gives back an observable of the result summary. Didn’t find anything in result-rx.js but did find a _summary tied to a ReplaySubject.

My stacktrace looks like this right now if it helps

TypeError: trx.run(...).summary is not a function

Thanks @zhenlineo, consume worked exactly like I expected after telling TypeScript to let me do my thing and thank you again for the link, must have missed that when upgrading to 4.x
