r.row is not defined in this context

[Sven65]

Describe the problem

Using r.row() in this query results in error

I've got the following function which I'm testing using this library and jest.

async addPlayerKills(kills: number): Promise<any> {
	return await r.table('users').get(this.user.id).update({
		playerkills: r.row('playerkills').default(0).add(kills),
	})
}

To test it, I'm using the following block:

test('Should add player kills', async () => {
	await user.addPlayerKills(1)

	const userData = await user.get()

	expect(userData?.playerkills).toBe(1)
})

But instead of getting any data, I get the error r.row is not defined in this context, from the line at https://github.com/aleclarson/rethinkdb-mock/blob/master/src/Query.coffee#L316

The user.get() method is just a simple call to r.table('users').get()

Environment:

Jest: 26.6.3
