Cannot delete files from firebase collection

I am following the example listed here, except with modifications due to the API of the new firebase-tools.

exports.clearMessages = functions.runWith({ timeoutSeconds: 540, memory: '2GB' }).https.onCall(messagesController.clearMessages)

export const clearMessages = async (data, context) => {
    const uid = context.uid
    const path = `users/${uid}/messages`
    return firebase_tools.firestore.delete('flightApp3', path, {
        recursive: true,
        shallow: true,
        allCollections: true
    }).then(result => {
        console.log('delete result', result)
        return result
    })
}

However, when I run this , I see the following displayed in Cloud Functions log:

However, I'm pretty sure I have an active project in my firebase CLI.

$ firebase use
Active Project: production (flightApp3)

Project aliases for /Users/myUser/Developer/flightApp3/cloud:

* default (flightApp3)
* production (flightApp3)

Run firebase use --add to define a new project alias.
