Intersect - "Must specify at least 2 geometries"

I'm using version 7.3.4 within a NextJS project.
The following code, lifted directly from the documentation:

var poly1 = turf.polygon([
    [
        [-122.801742, 45.48565],
        [-122.801742, 45.60491],
        [-122.584762, 45.60491],
        [-122.584762, 45.48565],
        [-122.801742, 45.48565],
    ],
    ]);

    var poly2 = turf.polygon([
    [
        [-122.520217, 45.535693],
        [-122.64038, 45.553967],
        [-122.720031, 45.526554],
        [-122.669906, 45.507309],
        [-122.723464, 45.446643],
        [-122.532577, 45.408574],
        [-122.487258, 45.477466],
        [-122.520217, 45.535693],
    ],
    ]);

    var intersection = turf.intersect(turf.featureCollection([poly1, poly2]));

Gives the following error on the final line: Must specify at least 2 geometries. I'm not sure whether the documentation is wrong, or there is a bug in the intersect function. If the former, what is the correct usage?

Start by comparing the intersect documentation linked in the report with the v7.3.4 function signature, then reproduce the supplied FeatureCollection example. Determine whether the documented call or the function behavior is incorrect, and confirm the corrected usage or behavior with a regression test before updating the documentation or implementation.
